NHAM Quartet: Tony Bevan/Jeb Bishop/John Edwards/Michael Zerang

Four UK/US free improv heavyweights reunite here for a tenth anniversary tour of their powerful NAHM quartet, featuring ferocious multi-reedist Bevan, here on depth-charge blasting bass saxophone. He's joined by Americans trombonist Bishop and drummer Zerang, and full-throttle UK bassist Edwards, all combining to create some serious, high-impact improvised music.
