The album named "Basement Echo" so far is the only co-work of this duo and it was released in Sep. 2008 by Important Records. As said Boomkat, the things went this way:
"The Acid Mothers Temple leader Makoto Kawabata teams up with fellow Japanese psych explorer Shinsuke Michishita of LSD March for this ear-melting guitar duel. It's an all-improvised affair with no overdubs, just fifty-five minutes divided into five tracks worth of dishevelled harmony, strips of feedback and a smart, restrained deployment of effects. Through whole sections of this record one guitar takes on 'melodic' duties, ponderously meandering through phrases while the other instrument summons up a wall of noise. There are other occasions where anything so ordinary as a 'note' is abandoned altogether, as on the furious whammy wrenching and distortion cloudbursts of the second piece. It's during these more searing exchanges that the duo's power comes to light, and you'd hope that this isn't the last meeting between these two figureheads of modern Japanese avant-rock."
The names of participants were intentionally "converted" into their European versions due to the Japanese specific order - in Japanese they prefer to use the inverted order of names-surenames so Europeans'd beware of the mistaggings.
