Live at the Us Festival is a live album and DVD by Canadianrock bandTriumph, released in 2003. The massive Us Festival took place over three days, outdoors in San Bernardino, California, on May 28–30, 1983. Triumph appeared on May 29, which was billed as "Heavy Metal Sunday" and included Ozzy Osbourne, Judas Priest, Scorpions, Mötley Crüe, Quiet Riot, and Van Halen. The number of attendees varied during the three days; the crowd was estimated to be about 500,000 strong on "Heavy Metal Sunday". The documentary-style part of the DVD gives a behind-the-scenes look at how their shows are put together; lighting, pyrotechnics, smoke, and lightning techniques are explained. Rik Emmett explains their songwriting process in his home. They interview celebrities like Ronnie James Dio that are at the show. Two videos are included, "Spellbound", and "Follow Your Heart", which showcases a live performance, all in DTS Surround Sound. Gil Moore and Mike Levine reminisce about the performance in a fifteen-minute interview from 2003.
