Evans can be a heavy hitter at the keyboard, but on his new album, he reins himself in a bit.

The English trio S.O.S. — saxophonists John Surman, Mike Osborne and Alan Skidmore — was formed in 1973, and made only one LP for the Ogun label a couple years later. They didn't last long, but they were the first of many horn choirs born in the '70s and '80s, mostly saxophone quartets.

On the clarinetist's latest album, the blues might be modernized or tweaked, but it's never far away. Fresh Air's jazz critic says The Edenfred Files is modest in a good way, like a musical chapbook or novella. The scale suits Harper's pointedly focused music.
