マザーズ・オブ・インヴェンション
Frank Zappa performed in Upland on Foothill Boulevard during the early 1960s where he played shows on a makeshift stage for college crowds. Zappa also purchased Pal Recording Studio on Archibald Avenue in Rancho Cucamonga where the Surfaris had recorded the surf music classic "Wipe Out". He dubbed it Studio Z and began making recordings that eventually led to the founding of Zappa's group The Mothers of Invention. Until his death in December 2012, singer Ray Collins of the Mothers of Invention lived in the area. Zappa mentions the Inland Empire in the song "Billy the Mountain".
