King, O.A.R.'s seventh studio album, opens with what will probably go down as one of the more idiosyncratic tunes in the group's catalog. Richly produced and boasting layers of texture, "King" is a swaggering rap-rock anthem featuring cameos from both Russell Simmons and DJ Logic. The rest of the record, in contrast, is a leisurely swim through more familiar waters: catchy pop and jam-band fun heavy on trustafarian grooves. It's a solid effort for sure, though it would've been nice had O.A.R. attempted to create a few more songs that exude the same ambition of that title track.
