Live concerts are meticulously coordinated events, with dedicated staff ensuring each instrument is tuned, each mic is working, and each band member is set in the upright and locked position. Keep their hard work from going to waste with today's GrouponLive for $18, you get one general-admission ticket to see Loudhaus at Brixton South Bay in Redondo Beach (up to a $21 value, including all ticketing fees) and attend an after-show meet and greet with the band (a $20 value) on Thursday, December 29, at 8 p.m. (up to a $41 total value). Doors open at 7 p.m. The spirit of '70s hard rock thrives as brawny Los Angeles trio Loudhaus cranks up the amps, bangs the skins, and knocks soaring vocals through the ceiling of Brixton South Bay. Previously known on the LA rock circuit as Bartholomew, the band has emerged like a phoenix rising from the witness-protection program to reintroduce itself as Loudhaus. The flocculent threesome recently flooded The Viper Room with their undiluted power of songs such as "I Am Not Your King" and continues its mission to free rock 'n' roll of wispy shackles during an opening set for seminal pop-rockers dada . Best known for the hit "Dizz Knee Land," dada celebrates the 20-year anniversary of its album Puzzle by playing the record in its entirety, first acting out the liner notes, then shrink-wrapping themselves. After Loudhaus's set, fans are privy to a special meet and greet with the band, where they can ask questions, take pictures, and absorb the sweet musk of flambéed rock. Today's deal also includes an autographed photo, and fans can bring other items for Loudhaus to sign, including T-shirts, belated Christmas cards, posters, and third-party checks.
