iHeartRadio Wango Tango, commonly referred to as simply Wango Tango, is an annual day-long concert produced by local Los Angeles radio station KIIS-FM. The concert series has been staged at various venues around southern California including Dodger Stadium in Los Angeles, the Rose Bowl in Pasadena, Angel Stadium in Anaheim, Verizon Wireless Amphitheatre in Irvine, Staples Center in Los Angeles and at the StubHub Center (formerly Home Depot Center) in Carson, CA. The concert series is noted for featuring several marquee performers in a day long series of sets. Often, noted celebrities are on hand to introduce each act. The concert concept was conceived by then marketing director Von Freeman and the General Manager of KIIS FM at the time, Roy Laughlin.
