California-based Plook lays down some nice instrumental jam with "Effday," a four minute track using just guitar, drums, and bass. The song has a cosmic vibe and funky, downtempo groove...perfect for a non-obtrusive background song at your psychedelic potluck or barbecue. "Effday" does not necessarily stand out in terms of genre-bending, but rather, puts its energy into solid rhythm and nasty, blues rock guitar solos.
