I was 12 years old when my older brother came home from college with a couple of Luna CDs, and they became my first favorite band. Ever since, Luna's bittersweet tunes have become the soundtrack for all of our reunions. Recently, the band announced its own reunion — including performing shows again and releasing a box set of vinyl reissues. For most people, that won't mean too much; the '90s rock group has long been, as Rolling Stone magazine put it, "the best band you've never heard of." But for me, it felt like another homecoming.
