This weekend Amsterdam’s mighty ICP Orchestra rolls through town for a series of performance as a full ensemble and in small groups. The group was founded by pianist Misha Mengelberg (who’s sitting out this tour) and drummer Han Bennink in 1974, and it’s existed ever since with a goodly amount of turnover (past members have included John Tchicai, Peter Brötzmann, Alan Silva, Enrico Rava, Giancarlo Schiaffini, Steve Lacy, and George Lewis, among numerous others), though the current lineup has remained more or less the same for a decade and a half. Yet before this particular ensemble started, Mengelberg and Bennink had a very long history together dating back to 1961: in 1967 they formed Instant Composers Pool with reedist Willem Breuker as a musical cooperative. Among its efforts was launching a record label to chronicle some of its activity.
