Hélène had asked me once whether I sometimes play along a record, and inspired by a video of Ari Hoenig I had watched in the morning, I played for half an hour over a Steve Kuhn/Scott La Faro/Pete LA Roca version of “Little Old Lady” (from their recording 1960). Then I practiced some fast comping (not so fast, 200 BPM), and I ended up with these one-measure grooves from John Riley's The art of bop drumming.
