Guitarist and viola player Tetuzi Akiyama, a founder of the Hikyo String Quintet in 1994, embodied the avant-jazz version of John Fahey's improvised solo acoustic guitar tradition on Relator (february 2001) and Pre-Existence (2005). The "onkyo" aesthetic was prevalent on Resophonie (august 2002) for "prepared resonator guitar" and Terrifying Street Trees (june 2003) for tape-delayed guitar.
Don't Forget to Boogie (july 2002) instead documented his "boogie" theory: minimalistic repetition a` la Steve Reich of blues riffs.
Route 13 to the Gates of Hell (may 2004) and Striking Another Match (april 2005) were live albums.
Among his numerous collaborations, Proletarian Drift (april 2003) was a live improvisation between Dutch lute player Jozef van Wissem and Akiyama on a nylon-string resonator guitar tuned to the same tuning as the lute.
Akiyama sang on the EP The Ancient Balance To Control Death (Western Vinyl, 2008).
Varianter Av Døde Trær (december 2007 - SOFA, 2008) and
Selektiv Hogst (december 2008) debuted the ensemble
Tetuzi Akiyama (on acoustic guitar) and composer and pianist Takuji Kawai improvised Transition (september 2009).
