Free jazz is like abstract art. And like those people who look at a Jackson Pollock painting and say their kids could do better, detractors of free jazz often make similar remarks. Free jazz’s emphasis on improvisation, experimentation, and extemporization over melody, rhythm, and tone can confuse listeners on how to best approach it. The answer is deceptively simple. Just listen without expectations and get caught up in the inventiveness of creation. This is a preamble to a discussion of tenor saxophonist Ivo Perelman’s most recent two releases with bass clarinetists, Kindred Spirits (Rudi Mahall) and Spiritual Prayers (with Jason Stein).
