Resonance Records has just issued a pair of archival releases from legendary saxophonist Stan Getz, recorded at the Keystone Korner in San Francisco.  The first, Getz/Gilberto ’76, captures a rare performance between two giants of bossa nova, Getz and vocalist Joao Gilberto.  The second, Moments in Time, features Getz with a phenomenal trio of musicians.  We chat with label Vice President Zev Feldman, who also produced these two sets, on how he tracked down these hallowed recordings.  Plus, he discussed the recent Wes Montgomery treasures that the label issued.
