This two-night Mercy Lounge benefit for YEAH’s Tennessee Teens Rock ‘n’ Roll Camp will kick musical theatre ass because 1, Les Miserables has an awesome score and the production itself is more opera than musical because it’s dialogue-free, and 2, the creme de la creme of Nashville is both singing the songs and part of the orchestra. Namely, Jordan and Alex Caress, Erin Manning, Raul Panther of Protomen, Larissa Maestro of Uncle Skeleton, etc. Starts Dec. 7 at 8 p.m., $15 in advance, $18 day of.
