Given the following context:

Mercury booked the New York Dolls at The Record Plant in New York City, where they recorded their self-titled debut album in April 1973. Rundgren was originally concerned that they had taken "the worst sounding studio in the city at that time" because it was the only one available to them with the short time given to record and release the album. He later said that expectations for the band and the festive atmosphere of the recording sessions proved to be more of a problem: "The Dolls were critics' darlings and the press had kind of adopted them. Plus, there were lots of extra people around, socializing, which made it hard to concentrate." New York Dolls was recorded in eight days on a budget of $17,000 (equivalent to $96,000 in 2018). With a short amount of studio time and no concept in mind for the album, the band chose which songs to record based on how well they had been received at their live shows. In Johansen's own words, "we went into a room and just recorded. It wasn't like these people who conceptualize things. It was just a document of what was going on at the time."In the studio, the New York Dolls dressed in their usual flashy clothes. Rundgren, who did not approve of their raucous sound, at one point yelled at them during the sessions to "get the glitter out of your asses and play". Sylvain recalled Rundgren inviting Buell and their Chihuahua to the studio and putting the latter atop an expensive mixing console, while Johansen acknowledged that his recollections of the sessions have since been distorted by what he has read about them: "It was like the 1920s, with palm tree décor and stuff. Well, that's how I remember it, anyway." He also said Rundgren directed the band from the control room with engineer Jack Douglas and hardly spoke to them while they recorded the album. According to Scopa, the group's carefree lifestyle probably conflicted with Rundgren's professional work ethic and schedule: "He doesn't put up with bullshit. I mean, [the band] rarely started their live sets before midnight,...
