live performance recordings

live interactive pieces in hmsl
mostly from the 1980s, early 90s

(note: some of these pieces have been released on cd in other versions, and are described in the article  "Live Interactive Computer Music in HMSL, 1984-1992," Computer Music Journal, 18(2):59-77, 1994)


Live concert by Nick Didkovsky and LP
Experimental Intermedia Foundation, 12/13/91

Slippers of Steel...
3 Improvisations for Guitar and Software Delay
some talking
51 Melodies

This was probably the premiere of Slippers... (we only did it a few times, but a slightly edited version is released on The Time is Now CD), and 3 Improvisations...., and 51 Melodies.

is described in the CMJ article on "Live ...  Music in HMSL..." (and is co-written by me and Nick). 3 Improvisations... used an Amiga-based, pretty flexible software delay system I wrote in HMSL that died with the Amiga. 51 Melodies has Leo Ciesa on drums, Greg Anderson on bass.

51 Harmonies

electric guitar, three percussionists, 4 computer (1 master, 3 "slaves"), several samplers. Trio Le Cirque, percussion; LP, electric guitar. Koln, Germany, June 17, 1994. Commissioned and recorded by the WDR Koln, and the Basel Conservatory Electronic Music Studio. Performed at the Koln Computer Music Festival.

This piece was performed  once. It involved a fair amount of gear (4 computers, samplers, a lot of percussion), and is  difficult. The HMSL code was  complex as well, with one computer controlling the playback of three other computers, and also providing live real-time generated notation instructions to the players. I've never had the opportunity to do it again, and problably won't now that HMSL is gone. There is, however, a stand-alone score (theoretically the piece can be done as an instrumental work, with the addition of keyboard instruments as well).

I've never written about this piece, nor has anyone ever heard it aside from those who attended the concert and any broadcasts it's had on the WDR (which I don't know about).

The WDR recorded it in the afternoon. They have, as far as I know, the only master tape. We performed it in the evening. This mp3 is a copy of the cassette  they gave me, which I believe was of the recording session. The recording is quite live, and "roomy",  and I don't think the sound balance in the room was ever quite right from a reinforcement point of view (there were mics on all the insruments). This is an mp3 of a dub.

(this concert was a duet concert with John Bischoff, but also had performers Jody Diamond, and Daniel Goode on it)

(This concert was a bit infamous, in that half of the concert (17 Simple Melodies ... and B'rey'sheet) didn't work, because of the intense cold and voltage spikes blowing out a home-brew A->D converter I had. The EIF concert above had those latter pieces, and I jokingly referred to it as the "world's longest intermission".)

(Although I think this performance is cut off, this could be the first performance of the piece).

Three Studies
Downtown Ensemble Concert, 6/7/90. LP, computer. Peter Zummo, trombone, Daniel Goode, clarinet. These pieces were written for this concert, and only performed a few more times (at Darmstadt, at Telluride, maybe some other places). They are perhaps my favorite live HMSL pieces from that period.

17 Simple Melodies of the Same Length

Studio recordings, Daniel Goode, P.A.S.S Harvestworks, NYC, around 1990. "2 versions of the piece with 2 computer versions each" (that is, the piece is broken up out of its normal performance sequence, but I'm not exactly sure, anymore, what these files are). Dub from cassette which is a dub from F-1 audio. Not exactly sure what the first version is (appears to have clarinet with the MIDI response part...).

Horn (for live electronics and french horn)

Chris Bobrowski, horn. March 2, 1990, live concert, Mills CCM. Dub from cassette which is dub from DAT. I think that this version is significantly different from the version on my Artifact CD Simple Harmonic Motion, in that it was done with a couple of Yamaha FBO1s, using live HMSL software (whereas the CD used HMSL to generate a Csound score).

Another live performance of Horn, recorded badly (overmodulated), but nice performance, from Experimental Intermedia Foundation, 4/29/90. This was a concert with Nick Didkovsky, and also had a trio version of Simple Actions (Part 1, Part 2) with LP, ND, and Chris Bobrowski, as well as a piece for guitar and computer called Duet (one of a series of pieces I wrote for me and Nick and HMSL).

The World's Longest Melody (piano study)

RPI, 1/31/96. I did several long solo improvisations using the TWLM software, before realizing the shorter studies that appeared on the CD Hallways.
This one was preceded by a long spoken introduction about the piece.

Always Move Towards the Baseline

For trumpet and live computer (HMSL). Ed Carroll, trumpet. Dartmouth College, 4/18/95. This piece was only performed a few times, perhaps the last live HMSL piece I did.

early HMSL recursive "feedback" experiment

Not a performance, but a recording unearthed and documented by my friend/colleague Scot Gresham-Lancaster of an early HMSL experiment we did at the Mills CCM
