Hot on the heels of The Avalanches and The Vines, the latest hot tip from Down Under arrives on a wave of media hype?and for once it’s not undeserved. The Sleepy Jackson is the year’s first great summer pop album. “Good Dancers” and “Sunkids” rival the gorgeous shimmering tunes of The Delgados, and “Caffeine In The Morning Sun” is pure Beatles, a simple but effortlessly cool melody. Only the drone-rock of “Let Your Love Be Love” misfires in this context. It’s as sketchy as mini albums usually are, but the band have undeniable promise.
