Music achieves its full emotional effect only when performed live, just as great literature becomes comprehensible only when screamed aloud in a crowded subway train. Enjoy public performance with today’s deal: for $12, you get one general-admission ticket to see Get the Led Out: The American Led Zeppelin at Lynn Auditorium on Friday, December 2, at 8 p.m. (a $27 value). Doors open at 7 p.m.

Philadelphia-based sextet Get the Led Out inhabits the sound and spirit of the biggest rock band of the ’70s, mesmerizing fans with its musically accurate portrayal. Formed out of a passionate love of Led Zeppelin and a need to replenish the nation’s dwindling classic-rock reservoirs, the members of Get the Led Out inhabit their heroes’ essence, nailing every note, nuance, and occasional charley horse. In a set that stretches across the legendary British group’s career like a pair of eight-legged spandex pants, the band re-creates a quintessential ’70s experience, earning roaring applause from fans and approving gusts of hair-ruffling wind from John Bonham’s ghost.
