While recording their fifth studio album, Paul Gilbert announced his decision to leave the band, and new guitarist Richie Kotzen was added to the lineup. The new line-up of Mr. Big released "Get Over It" on September 1999 in Japan. "Get Over It" yielded "Superfantastic", a number one hit in Japan that went multi-platinum. It proved to be Atlantic's biggest selling release in that territory. Mr. Big put in a 20-date tour of Japan followed by a rousing New Year's Eve 1999 show with Aerosmith at the Osaka Dome in Osaka. "Get Over It" was released in the U.S. on March 21, 2000, followed by a short club stint at The Roxy Theater in West Hollywood.
