Story of I (1976). Since working with the Brazilian ballet, he became interested in percussion and travelled to Colombia, Bolivia, Chile and Argentina for inspiration, and arrived in Brazil where he gathered "a very, very strong unit of 16 percussionists" to play on his album. Moraz invited synthesizer inventor Bob Moog to contribute sounds on the album; Moog accepted the task, and worked with him for several weeks. During this time Moraz also played on Steve Howe's album Beginnings (1975) and Chris Squire's album Fish Out of Water (1975). Moraz travelled to Brazil and incorporated Brazilian rhythms and musicians on The Story of I, giving it a world music flavour. Afterward he returned to Yes for their 1976 North American tour, where the band headlined several large concerts. After the 1976 tour, Yes retreated to Montreux, Switzerland, to record their next album, Going for the One (1977). Some of the material had already been worked out by the time of their arrival; this included contributions to "Going for the One", "Wonderous Stories" and "Parallels" from Moraz. However, during the early sessions, Moraz was told to leave in order to allow Wakeman to return to the band. Moraz spoke about his departure: "Even though, at the time, the split 'was not made to appear acrimonious', I suffered extremely and extensively. To be 'asked to leave' so suddenly put me in a lot of turmoil and disturbance ... I was never compensated for anything. I never ever got paid for any of my tour participation in the ... tour of 1976 ... I was entitled to a 20% cut from what the band was getting." Moraz continued with his solo career and released his second album, Out in the Sun (1977), which he wanted to sound "completely different and more liberated". He then moved to Brazil for a year and a half, and prepared material for his third album, Patrick Moraz (1978). During his time there, Moraz joined a Brazilian rock band, Vimana, with Lobão and Lulu Santos and Ritchie. He also recorded the keyboards in one of the most iconic songs of Brazilian music, called "Avohai", by Zé Ramalho. 1978–1991: The Moody Blues and solo projects In May 1978, Moraz visited a convention held by the Audio Engineering Society in Los Angeles, where "Herbie Hancock taught me how to use the vocoder" and agreed to represent Aphex Systems in Brazil.
