When you hear that a band is coming to town to perform all its songs from one, specific album, you might think, "Meh. Boring. I'll save the $35 and listen to the CD I've listened to a couple thousand times." But when that band is the Pixies, the album is "Doolittle" and the set list exactly mirrors the album, you might think, "That show would be amazing." And you'd be right. The Pixies played a packed show at the Eagles Ballroom Saturday night that, with two encores, gave serious fans their fill.
