Back in the '90s, there was a cluster of like-minded indie-pop artists called Elephant 6. If bloggers had been around then, they undoubtedly would've spent a huge chunk of their day typing praise about all the Elephant 6 bands. Some of the groups are still around: Apples in Stereo, Of Montreal. Many of them — like the great Neutral Milk Hotel and Olivia Tremor Control — disappeared long ago. Athens, Georgia's Elf Power was one of the collective's founders, and 14 years after its debut album, it's still making elaborate records loaded with fancy instruments and classic pop hooks. The just-released In a Cave — Elf Power's ninth album — finds frontman Andrew Rieger still piling on layers of sound and random lyrics. Should be a real treat live.
