Ernesto Rodrigues’ fine—and very productive—Creative Sources imprint has rocketed into the forefront of improv imprints specializing in various strains of electroacoustic and “lowercase” musics (the labels are oft-debated, so insert asterisks as you please). The latest batch of releases isn’t as consistent as one might hope for, but there are still many rewarding discs, some exceptional moments, and a much-appreciated opportunity to hear new musicians at work.
