The Extradition Series 2018 Spring Concert will take place on Saturday, April 21 at Leaven Community, PDX, featuring five works of extraordinary experimental composition:

> Richard Glover, “An Imperfect Harmony” (2013): A simple, deeply resonant composition exploring microtonal harmonies on the double bass. The piece will be performed by Andre St. James (double-bass).

> Catherine Lamb, “Nodes, Various” (2009/10): Using a defined frequency set, this open-ended piece asks a group of musicians to explore the tonalities of saw-wave oscillations and their low overtones. The piece will be performed by Matt Carlson, Derek Ecklund, Ben Glas, Branic Howard, Juniana Lanning, and Evan Spacht (electronics).

> Mark So, “a tepid atmosphere (bedroom near the sky)” (2007): Part of a series of pieces based on the poetry of John Ashbery, “a tepid atmosphere” combines field recordings, electronics, and other instruments to slowly shift the listener’s perspective within what seems like a static sound environment. The piece will be performed by Matthew Andrews (vibraphone), Brandon Conway (guitar), Mike Gamble (guitar), Matt Hannafin (percussion), and Branic Howard (electronics + field recordings).

> Jurg Frey, “Floating Categories” (2015): Scored “for reader, listener, player alone, maybe performer(s),” this sparse dreamscape mixes words and phrases, short melodic fragments, and grids of colored dots, challenging performers to translate images and feelings into aural and visual content. The piece will be performed solo by Loren Chasse (sound + light) with pre-recorded melodic fragments by Matt Carlson (piano), Douglas Detrick (trumpet), Matt Hannafin (melodica), and Jacob Mitas (violin).

> Michael Pisaro, “Entre-Moments” (2005/6): Combining separate pieces for piano, instrumental trio, and group electronics, “Entre-Moments” is concerned with projecting a sparse amount of musical material across long durations. This performance will be the world premiere of the combined piece, performed by Matt Carlson (piano), Lee Elderton (clarinet), Catherine Lee (English horn), Andre St. James (double bass), and Derek Ecklund, Ben Glas, Branic Howard, Juniana Lanning, and Evan Spacht (sine tones).

> Ben Glas, “Self Composure #2 (Memory Sequence)” (2018): Part of our participatory “Extradition Off-Site” series, this new sound meditation by Portland composer/performer Ben Glas is designed to be performed by anyone, musician or non-musician, outside of the concert setting, at the time and place of their choosing. The score will be available as a Facebook event within a four-week window around the concert date. (Check www.facebook.com/TheExtraditionSeries)
