Mingle, the Saturday Knights' debut album, is Seattle's first summer blockbuster. MCs Tilson and Barfly are genial block-party hosts, dishing up goofy punch lines and technical tongue twisters like so much hot barbecue. DJ Suspence straddles genres, presiding over warm breakbeats, wheezy soul organs, horns, piano, and bitchin' Camaro guitars. With Daptone's the Budos Band opening (and possibly sitting in with the Knights). More than a record-release party, this is the official start of the summer party season.
