I had a theme for this week’s show already in the works when Cyclical Dreams released the new album by one of my favorites, Michael Brückner. Upon listening to it, I felt I wanted to feature it but, even more, I felt it would be worth highlighting Michael’s music in general. So this week’s show will consist entirely of music created by Michael Brückner. Tune in to hear why he’s one of my favorite artists.
I was watching a live YouTube performance by Bill Astro Music this week that I found inspiring. I asked him if he'd send me a recording of the track to share on the show, which he graciously did. That made me dig in the archives for more recordings of live on-air performances, and so that is the focus of this week's episode of The Main Sequence. Tune in for some extended pieces from Bill Astro Music, State Azure, Martin Stürtzer, and Caught In Joy.
August 08 2026 - We are living in heady times as far as the amount of new music being created, performed, and released. While I just did a “NEW MUSIC” show last week, I just acquired (thanks in no small part to Bandcamp Friday) quite a few brand new nuggets of joy. And so I will share them with you. Tune in for new music from Arjen Schat, Thaneco & Romerium, Robert Rich, Michael Brückner, and more.
August 01, 2026 - While the show will not consist entirely of new releases, I’m going to call it a new release show just to put a shine on it. Of course, if you haven’t heard any of the music I’ll be playing then it’s all new to you anyway. The bottom line is to be prepared to be entranced by music that will be fresh to your ears.
This week I added several new artists to the Main Sequence library, including renowned dungeon synth artist, Jim Kirkwood. So we introduced some new music. Then there were some tributes to Klaus Schulze and plenty of other great music.
Threw this one together pretty quickly, but I'm happy with the combination of tracks that emerged. The time spanned in the show goes from 1987 until just this week. There continues to be an inspiring body of this music being produced. Listen and enjoy.
July 11, 2026 - Once again, I don't plan a theme but during the show one seems to emerge.... This show came to focus on quite a few free and "name your price" releases, both old and new. It takes me back to hosting Free Floating where all of the music was available for free download. So if there's something you really like here, check out the links and pick it up for free (or toss the artist whatever you want). A lot of great music here.
July 4, 2026 - There was no theme when I put this show together, but in the midst of it I felt that it could be called "Eponymous" due to the number of Album/Track/Artist names that coincided. The show welcomes a new artist, Caught In Joy, to the fold and (unsurprisingly) features the latest Cyclical Dreams release from Adam Filip.
June 27, 2026 - This show was another NEW MUSIC feature. I recently added a whole lot of music to The Main Sequence library–some new releases, some newly discovered older music via the Internet Archive. It’s new to me, so I’m going to share it with you.
On this week's episode of The Main Sequence, I feature the work of Peter Baldwin, AKA The Rosen Corporation. I lean heavily on material from the three recent retrospective releases celebrating 10 years of The Rosen Corporation but with some other favorite tracks thrown into the mix.
Come with me on our weekly journey through caverns of echoing pulses, swirling cascades of ringing sound, drifting abstract rhythms. These days the machines can feel ominous but we can find where their songs and ours come together… We celebrate the 6th anniversary of the Cyclical Dreams label with a few tracks, old and new. We welcome Bill Astro Music to the RadioSpiral artist community, and preview a show dedicated to The Rosen Corporation. And more...
June 06, 2026 - This week’s show is about going with the flow… Which means exploring some longer tracks (though maybe not as long as during The Long March). The show consists of three pieces by D*Time, Michael Brückner, and grum-pe. Each has the time to grow and shift and flow and transform, some of what this kind of music can do best.
This week's show was by the seat of my pants--no playlist, no prep. Just go with the music that seems right at the time. I think it came out rather well. Listen and let me know if you agree.
May 23, 2026 - If you have listened to The Main Sequence at all, you have heard a release from the Cyclical Dreams record label. Their work is a feature of the show, and for good reason. Pablo, Lucas, and Esteban release consistently high quality music from an ever growing stable of electronic artists. So this episode of The Main Sequence is dedicated entirely to works from Cyclical Dreams, including the new release from Cells Interlinked, Cold Spring Notes. https://cyclicaldreams.bandcamp.com/music
May 16, 2026 - This week’s Main Sequence is dedicated to an artist that I discovered last year and whose work I have been increasingly drawn toward. (Luke) L. V. Morris makes consistently rich sequenced Berlin School-styled music. His sound design is generally warm and uncrowded, the pulses and sequences developing into deliciously enticing sonic immersion. Tune in as we explore some of Luke’s music. https://lvmorris.bandcamp.com
There are many of ways to construct the playlist for a show. One of them is by finding songs in the same (or related keys). This week the focus is on G-minor. Playlist: No Track Artist Album 1 Shadowed Genesis DTime Nightwoven 2 Void Among Stars DTime Nightwoven 3 Trisolar Martin Stürtzer Relativity 4 Whispered in My Ear Paul Ellis Room of the Lost One 5 Chase the Evening Wavestar Moonwind 6 To A Distant World (Part 3) State Azure To A Distant World 7 Le Modulor Pabellón Sintético Machine For Living 8 Into the Void X-Orbital Interstellar Encounters 9 Holomorph Arjen Schat Infinite Arithmetics
I went on a bit of an acquisition binge yesterday for Bandcamp Friday. And so I have plenty of new music to share with you this week. Some are new releases, some are re-releases, and some are artists who are new to the show and RadioSpiral.
I'm not that good at coming up with themes for the show at this point. Most of the time it comes down to, "Hey, here are some great pieces I think you should hear...." This is one of those shows. Just some really good music that maybe you don't know (but should).
Let's call this one a time machine, as we delve way back into a cassette release from the early 1980s all the way up to brand new releases...
In honor of the current Artemis II mission to the moon, this show focuses on lunar themed pieces. The association between synth music and space exploration is legendary, so this is a perfect fit. A lot of great music to hear from some Main Sequence favorites.
For the final installment of this year's Long March, we start with Arc of Passion by Steve Roach, continue with a live concert from Arjen Schat, and then conclude with a piece from DTime.
The focus this week was on a piece by Chuck van Zyl from his Passages album, The Face of the Night, clocking in at about 78 minutes. To warm you up there's a great piece from The Soviet Space Dog Project. Enjoy how the music grows and develops across these long form pieces.
Mar 14, 2026 - The Long March progresses this week with something really long, the Star Seed track from The Rosen Corporation clocks in at over 1 hour 18 minutes. It goes through a lot of moods. Then we hit Sophos' performance from Cyclical Fest 2023 which starts with jagged tones and then blossoms into full sequences....
Mar 7, 2026 - The first installment of The Long March where I feature long-form pieces (30 minutes or more). Two great tracks from State Azure and Michael Brückner.
I had some technical issues (mostly with my mic) during the show and so this is a reconstruction of the show. There's something from the mysterious trio, Dream Sequence, and new artists Yakuzza Jakuzzi and The Rosen Corporation.
