In September 2003, My Morning Jacket released its third album
It Still Moves. It was the band's first album to be released by
ATO Records. During the subsequent tour, guitarist Johnny Quaid and keyboardist Danny Cash quit the band on amicable terms, and were replaced by guitarist
Carl Broemel and keyboardist Bo Koster. Drummer Patrick Hallahan said that while the arrival of new members put the band in an awkward position, it was also a liberating experience. "We thought, 'Let's take ourselves out of our element.'" For the next My Morning Jacket album, the band members wanted to experiment with unique arrangements and a greater usage of musical
soundscapes when compared to their previous albums. Vocalist
Jim James said the band went out of their comfort zone, and decided to record the album at the remote Allaire Studios in the
Catskill Mountains instead of in their hometown of
Louisville, Kentucky. According to bassist
Tom Blankenship: "We had been talking for years about really locking ourselves in when we did an album, and now there was no excuse but to be in the studio all the time. You'd wake up and have breakfast and grab your coffee and walk into the control room."
Z was the first My Morning Jacket album to have a professional producer. James had previously produced every album, which he said was out of pride. James said Leckie's perspective as an outsider played a pivotal role in the production of the album. According to James: "Sometimes when everybody in the band is just there, you know, people don't want to hurt anyone's feelings, or you might think that it was a good take because everyone is tired. We really learned the value of having another ear there." ==Composition==
