For a brief moment, Band of Horses were a well-loved Seattle secret known as simply Horses. Now, the band is neither Seattle's—they've relocated to singer Ben Bridwell's native South Carolina—nor are they anybody's secret: Tonight's homecoming at the Showbox is sold out. For those with tickets, or willing to buy some from a scalper, this concert could be a rare preview of the band's new album, which they've been in town mixing. See an interview here. (Showbox, 1426 First Ave, 628-3151. 8 pm, $15, 21+.)
