The lead track from the Sea and Cake’s forthcoming album Runner sounds like it was written on sequencers, which is always impressive coming from a band that started out specializing in African-inspired jazz fusion in the mid-90’s.  “Harps” breezes by amidst a backdrop of chimes, strings, and glowing synths which have a “happy gas” effect — nobody will be able to harsh your mellow after this one’s over.  Still, with lyrics like “I couldn’t let go” and “The sky was never blue,” frontman Sam Prekop never lets you forget what discomfort feels like.  It’s a dreamy dichotomy, par for the course for this indulgently creative albeit risk-taking group.
