some recognition and earn money. Some of that recognition came from their performance at the Sky River Rock Festival and Lighter Than Air Fair, occurring over the 1968 Labor Day weekend in Sultan, Washington. Sky River is considered by many to be the first successful multi-day rock festival, and a number of major bands had the opportunity to hear It's a Beautiful Day there. The band got its first big break when offered a chance to open for Cream at the Oakland Coliseum, in Oakland, California on October 4, 1968. Around this time, the band first began a long process of trying to disentangle themselves from Katz. The band's debut album, It's a Beautiful Day, was produced by David LaFlamme in Los Angeles, California, and released by Columbia Records in 1969. It features tracks such as "White Bird", "Hot Summer Day", and "Time Is". The album reached number 47 in the U.S. charts and number 58 in the UK. The theme from the song "Bombay Calling" was later used, at a slower tempo, by Deep Purple as the intro to "Child in Time" on its Deep Purple in Rock album. The band retaliated by recording "Don & Dewey" which was, to all intents and purposes, identical to Deep Purple's "Wring That Neck". The vocals and violin playing of David LaFlamme plus Santos's singing attracted FM radio play attention, and nationally, "White Bird" bubbled under Billboard's Hot 100 chart, peaking at number 118. 1970s and beyond By 1970, the original lineup of the band had changed; the LaFlammes had split up and Linda left the band, replaced by Fred Webb. On July 5, 1970, the band played the second Atlanta International Pop Festival in Byron, Georgia to an estimated 250,000 people. The group's second album, Marrying Maiden, recorded at Pacific High Recording Studios in San Francisco, was released in 1970. It was their most successful on the charts, reaching number 28 in the U.S. and number 45 in the U.K. In that same year, the band performed at the Holland Pop Festival at the Kralingse Bos in Rotterdam, Netherlands, and at the Bath Festival of Blues and Progressive Music. It's a Beautiful Day was one of the last acts to appear at the Fillmore West in San Francisco in July 1971. Its performance of "White Bird" was featured as part of the musical documentary film Fillmore, released the following year. Mitchell
