Before radio, music was broadcast via Morse code, which turned everything into treble-heavy dance music punctuated by demands to STOP. Jam out to monosyllabic beats with today’s GrouponLive deal: for $12, you get one ticket to see the 11th annual Maxt Out dance competition, presented by Jayvee Dance Productions, at the San Gabriel Mission Playhouse on Sunday, November 6. Doors to the theater open at 11:30 a.m., and competition events run from 12 p.m. to 6 p.m.

Dance crews from the West Coast’s strongest bastions of hip-hop culture converge on the San Gabriel Mission Playhouse for a full day of breakdance battles and other street-cred-boosting showcases. The stage creaks and whimpers in protest as more than 600 dancers from across California hop, skip, and stop through routines that pit the art of choreography against the laws of physics. Those who arrive before the doors open can start the day off with the dizzying spectacle of a Maxt Out Breakdance Battle held in front of the playhouse. After the breakers and b-girls heat up the pavement to egg-frying levels, visitors can head inside to enjoy a blast of coolness courtesy of the junior and professional dancers kicking off the hip-hop and choreography contests.

Visitors receive a wristband that allows them access to both the indoor concert and outdoor mini-festival, which includes access to a cavalcade of gourmet food trucks and booths set up by local vendors.
