Recorded in Liverpool back in 2003, this improvised performance unites two of the UK's foremost improv exponents (Tony Bevan and Paul Hession) with two pioneers of modern free music, the multi-talented guitarist, turntablist and noise artist Otomo Yoshihide and the late, great Derek Bailey.

The performance shuffles into first gear during the speculative, tentative first throes of "No Hiding Place/Softly Softly", establishing a ruthlessly abstract sound world from the outset, only to tighten up slightly for "Morse", which welcomes a far more full-blooded, often swing-influenced approach to percussion, accompanying Bailey's lightly overdriven, spidering guitar lines.

The remainder of the set introduces some charged-up, visceral reed work, sounding surly and untethered on "Good Cop, Bad Cop" while Bailey playfully plots a more welcoming path.
