LUNASA This Irish quintet’s intricate, groove-driven acoustic sound makes them one of Celtic music’s most highly regarded modern instrumental groups. Revered like rock stars back home, Lunasa take traditional Irish instruments, fiddle, pipes, flute and guitar and shift them into rhythmic overdrive with intricate arrangements. At the center of their sound is the playing of double bassist Trevor Hutchinson, whose time signatures lead the group toward the innovative turf of acoustic music leaders like Bela Fleck and Darol Anger. Lunasa’s new album, Sé, came out last month on Nashville’s Compass Records; seeing the group in a venue this intimate should be amazing. ( ) Gibson Musical Showcase (MICHAEL McCALL)
