Katy Perry to Rock Pepsi & Billboard's 'Summer Beats'

Pepsi and Billboard are kicking off their "Summer Beats" live series in a big way. The first event will feature Katy Perry in a special live performance at an as-yet-unannounced location in Los Angeles on June 26 as part of the official U.S. premiere event for her new Paramount Pictures film, "Katy Perry: Part of Me," that opens everywhere in theaters July 5.

The Katy Perry special live performance will be live-streamed on Twitter, and fans tweeting about the event can use the hashtag #KatyPerryNow.Fans can also help directly influence elements of the performance in real-time by following directions from @ Billboard and @ Pepsi.

Billboard and Pepsi have given away over 300 tickets to local Katy Perry fans via a series of Tweets that reveal pop-up street teams around Los Angeles. Fans can try to find the "Summer Beats" street team in L.A. one more time today, at a location and time announced on the Billboard Twitter account (stay tuned).

Global music fans can watch the program on Pepsi's Twitter page (@Pepsi) or on Pepsi.com starting at 6 p.m. PST. Billboard.com will help promote each concert as well as host on-demand streams of each concert following the show.

Following Perry's live performance will be a late-July show in Nashville and a late-August event in New York. Featured artists will be announced at a later date.
