Live music unites people from all walks of life, unlike silence, which only unites librarians and people who crack safes. Bond over shared sound waves with today's Groupon: for $20, you get one general-admission ticket to the OC Fair New Year's Eve Block Party (up to a $40 value). The event takes place at the OC Fair & Event Center in Costa Mesa on Saturday, December 31, from 7:30 p.m. to 1:30 a.m.

After a successful inaugural New Year's bash last year, the OC Fair & Event Center will once again lead partygoers into the pages of a fresh calendar with live entertainment, food trucks, and multiple cash bars. A dozen tribute bands will adopt the stage presence and crowd-surfing styles of legendary performers to represent four decades of music, transporting audiences with classic riffs from The Who, The Beatles, AC/DC, Pearl Jam, and more. After an aural odyssey through the past, guests can fan the flames of entertainment by absorbing Project Dynamite's outrageous act, which includes stunts, props, and potent doses of comedy. Meanwhile, a casino converts party faces into poker faces, and an array of food trucks mute premature countdowns from empty bellies with tacos, burgers, barbecue, and sushi.

At midnight, partygoers convene to greet 2012 amid fireworks, friendly smooches, and rampant brainstorming for the most creative way to break New Year's resolutions. View a video of last year's festivities here.
