version of the Alice Cooper song "Escape" from Welcome to My Nightmare). Ezrin flat out rejected most of the material, as only heavily re-worked versions of "God of Thunder" and "Detroit Rock City" made it to the album, and one song "Mad Dog" was pilfered for lyrics to "Sweet Pain" and a riff for "Flaming Youth". Other songs from this demo were re-worked for the following album Rock and Roll Over and Gene Simmons' 1978 solo album while others remained unreleased until the 2021 release of Destroyer as a 2CD set and Super Deluxe box set. The first recording sessions for the album took place on September 3–6, 1975 at Electric Lady Studios in New York City, during a brief break between the Dressed to Kill and Alive! tours. The basic album tracks were recorded during this time. The majority of the recording sessions for Destroyer took place in January 1976, after the conclusion of the Alive! tour. Ezrin introduced to Kiss sound effects, strings, screaming children, reversed drums (on "God of Thunder") and a children's choir. The song "Great Expectations" uses the first phrase of the main theme from the second movement of Beethoven's Piano Sonata No. 8 in C minor, Op. 13 (known as Sonata Pathétique), but the songwriting is credited to Simmons and Ezrin. During the recording sessions, Ezrin resorted to numerous tactics designed to increase the quality of music Kiss recorded. Because none of the group were trained musicians, Ezrin halted the sessions at one point to provide lessons in basic music theory. To instill a sense of discipline, he wore a whistle around his neck and exhorted the band with sayings such as, "Campers, we're going to work!" When Simmons stopped playing during the recording of an outro, Ezrin yelled at him, saying, "Don't you ever stop a take unless I tell you!" Paul Stanley later compared the experience of working with Ezrin as "musical boot camp" but said that the group "came out a lot smarter for it." Simmons echoed the sentiment by stating, "It was exactly what we needed at the time." Destroyer is the first Kiss album to prominently feature outside musicians, such as members of the New York Philharmonic. One musician not credited was Dick Wagner, from Alice Cooper's band, replacing Ace Frehley on the track "Sweet Pain". Wagner also played the acoustic guitar found on the song "Beth". The success
