Today's side deal takes recursive music to strange new places. For $20, you score a ticket (a $40 value) to Tributefest, which in itself is a tribute to the greatest concert that never happened, as duplicates of bands like The Who, The Beatles, and Sublime take to the stage. The concert starts on Saturday, May 1, at 11 a.m. and mirror-rocks nonstop until 10 p.m. in Santa Clarita's Central Park.

Every hour on the hour, a fresh band of glorifying imitators will precisely replicate the music of yesterday for today. See Stepping Feet (Dave Matthews Band), Petty Cash (Tom Petty and Johnny Cash), Joshua Tree (U2), The Who Show (The Who), Paperback Writer (The Beatles), and more. Not making an appearance is Most of the Left Side and the Middle of the Periodic Table of Elements (Metallica). As not-Bono will sing without once stopping everything to talk about Africa, it's even better than the real thing. There are no exorbitant costs, and faux–Steve Tyler is a Bikram yoga guru who wraps himself into the shape of the space shuttle from Armageddon. There's also a good chance that Ozzy Osbourne, lost on his way to the beach and mistaking Queen Nation for Black Sabbath, will make a special appearance as himself. Bands will play their band's top hits, as well as mimic their internal tensions and follow their VH1 Behind the Music rise-and-fall trajectory.

More than a dozen food trucks, 30 draft brews, and award-winning barbecue keep the atmosphere easy and the mood stoked. Dress up in your best impression of a rock fan and have a fun time dancing and eating to your favorite music.
