"Boston" was primarily recorded at Scholz's own Foxglove Studios in Watertown in "an elaborate end run around the CBS brain trust." Epic wanted a studio version that sounded identical to the demo tape, and Scholz decided he could not work in a production studio, having adapted to home recording for several years, stating "I work alone, and that was it." Scholz took a leave of absence from Polaroid, and was gone for several months to record the band's album. "I would wake up every day and go downstairs and start playing," he recalled. Scholz grew annoyed reproducing the parts, being forced to use the same equipment used on the demo. The basement, located in a lower-middle-class neighborhood on School Street, was described by Scholz as a "tiny little space next to the furnace in this hideous pine-paneled basement of my apartment house, and it flooded from time to time with God knows what." There was a Hammond organ and a Leslie speaker stuffed in the corner of the room alongside the drums; whenever it was time to record the organ parts, they would tear the drums down and pull out the Leslie. Boylan felt that while Scholz's guitars "sounded amazing," Scholz did not understand how to properly record acoustic instruments, and flew in engineer Paul Grupp to instruct him on microphone technique.
