KCRW’s Private Playlist is a weekly listening session with Southern California’s most notable musical figures in their private creative environments. The piece airs Friday mornings on KCRW as the closing segment of Morning Edition. For this installment, I spoke with guitarist Jeff Parker, whose career began with Chicago’s legendary Association for the Advancement of Creative Musicians (AACM). He rose to national prominence in the ‘90s during his tenure with “post-rock” ensembles such as Tortoise and Isotope 217. Since then, his studio credits have been as expansive and eclectic as his playing, including records by Andrew Bird, Meshell Ndegeocello, Rob Mazurek, Joshua Redman, the Aluminum Group, and more.
