With last year's debut, Trouble, Ray LaMontagne made critics swoon by mixing Neil Young's delivery with Patty Griffin's lyrics, and the fuss was worth it. But it's opener Rachael Yamagata you need to fight your way to the front to see. At her first Dallas concert, she'll prove why she's been the perpetual one to watch for three years despite having only one album under her belt. Fans who found her through last season's O.C. cameo are in for a surprise when they watch her light up a cigarette and transform glossy studio tracks into sultry jazz numbers.
