Jim Adkins may have sung his heart out. Having recently helmed two discs of impeccably propulsive emo-pop, cornering MTV in 2002 with the I’m-OK-you’re-OK “The Middle,” the Jimmy Eat World frontman now sighs through an EP of somber, chiming regrets. (Sparta’s Tony Hajjar provides backup.) Adkins and his band have always found heartache’s sweet spot. Here they elevate exhaustion, transforming it into something like longing. The nearly eight- minute “Disintegration” models itself on the stark, circular musings of someone recently dumped, with a knotty, booming drum beat, persistent guitar murmurs and, in the big finish, layered, competing melodies. Conventional and pretty, the remaining tracks are more literal, and less arresting, laments. Their yearning is our yawning.
