Like Ouija boards, concerts bring people into physical contact with the disembodied voices that croon nightly at their bedsides. Groove to some supernatural beats with today’s GrouponLive deal: for $10, you get one general-admission ticket to see Halloween with the MarchFourth Marching Band plus Rusty Lazer at House of Blues New Orleans on Monday, October 31, at 9 p.m. (a $19 value, including fees). Doors open at 8 p.m.

The House of Blues New Orleans' raucous Halloween celebration channels energy from bounce DJ Rusty Lazer before MarchFourth Marching Band storms the stage with eye-popping acrobatics, lush costumes, and a potent cocktail of horns, guitars, electric bass, and drums. The 20-member ensemble reinvents the marching band, fusing the celebratory sounds of a Boss's Day parade with the extravagant costumes of Mardi Gras and the dancers, stilt acrobats, and fire-jugglers of a circus. The troupe proudly declares that "no two shows are ever exactly alike," and Alibi describes the experience as a "concert extravaganza … a mash-up of big band, jazz, ska, Eastern European folk." Supporting the rowdy rhapsody, Rusty Lazer shows off the skills that have earned him buzz as one of New Orleans' best bounce DJs, drawing shimmies, shakes, and spare trampoline springs from the crowd during sensational call-and-response hip-hop.
