No record label has done more for the genre of jazz over the last decade than Resonance Records. The California independent has unearthed gems from a who’s who of jazz, from John Coltrane and Jaco Pastorius, to multiple releases by piano great Bill Evans and guitar master Wes Montgomery.

Those last two artists are the subject of Resonance most-recent projects. Evans in England features previously unheard live performances from 1969, while Back on Indiana Avenue culls a collection of studio and live tapes of Wes Montgomery right before he became famous.

We chat with Zev Feldman, the co-president of the label, about the crazy stories that led to unearthing these releases by two of the legends of jazz. He also tells us what new project the company is working on for the Christmas holiday.
