Bloodcount expand the envelope of musical form and substance. Discretion features a collection of Tim Berne’s never-played-before compositions with the leader on alto and baritone, Chris Speed on tenor and clarinet, Michael Formanek on bass and Jim Black on percussion. They recorded the five, no-holds-barred extended cuts (nearly 14 minutes each) during the group’s 1997 U.S. and European tours in New York, Munich and Iowa. This is the kind of music that drives audiences wild. They either love it, or leave. Judging from the ambiance on this CD, they loved it. What piques the interest repeatedly is the interplay between Berne and Speed, and the power and passion of Black’s energetic percussion.
