The first big hit recorded in the studios was Dave Edmunds' "I Hear You Knocking" in 1970. In the early 1970s, the studios were used to record seven albums by Budgie, several by Hawkwind, one by Hobo, Peter Hammill's second solo album "Chameleon in the Shadow of the Night" in 1973, Ace's hit single "How Long" in 1974, and Queen's album "Sheer Heart Attack". Queen first worked on developing their album "A Night at the Opera" and the song "Bohemian Rhapsody" for a month at Ridge Farm Studio during the summer of 1975, then moved to Rockfield in August 1975 to begin recording the album, which became the band's first Platinum-selling album in the US. Motörhead made their first recordings at the studios in 1975 and were, briefly, signed to the Rockfield record label. Cyril Jordan of the Flamin' Groovies (who recorded at Rockfield several times between 1972 and 1978) said in 2014, "We thought Rockfield was the new Sun recording studios."
