He also assisted on Pye Studios recordings by the Kinks, the Searchers, the Undertakers, Petula Clark, and Sammy Davis Jr. In 1964 he founded KPS Studios, a mono- and two-track facility which was acquired in 1965 by Regent Sound, where the Rolling Stones had recorded their first album. Regent then tasked Kramer to help build and run their new four-track studio. The Beatles had recorded "Fixing a Hole" there, later to be featured on their 1967 album Sgt. Pepper's Lonely Hearts Club Band. Kramer engineered two Beatles hit singles which appeared on Magical Mystery Tour—"All You Need Is Love" and "Baby You're a Rich Man". The two songs were recorded at Olympic Studios, where, in 1967, Kramer engineered albums for the Rolling Stones, Small Faces, Traffic, and Jimi Hendrix. Kramer became a permanent part of Hendrix's creative process, collaborating on the four albums which Hendrix released before his death in 1970. In 1968 Kramer relocated to New York, primarily to continue working with Hendrix. Headquartered first at The Record Plant and later working as an independent producer and engineer, Kramer produced the first Johnny Winter album and engineered a sequence of five Led Zeppelin albums, beginning with Led Zeppelin II. Kramer and his crew engineered the sound at the 1969 Woodstock Festival; they recorded the entire festival in a harried, sleepless, three-day binge. It required vitamin B shots for stamina, and was interspersed with brilliant performances from several of rock's then-reigning acts, as documented in both the film, Woodstock, and the three-disc album Woodstock: Music from the Original Soundtrack and More. 1970s Kramer began the second decade of his career working alongside architect John Storyk to oversee creation of Jimi Hendrix's state-of-the-art studio, Electric Lady Studios, built and equipped for a then-astonishing $1 million. He served as Director of Engineering there from 1970 to 1974, producing Carly Simon's debut solo album, Carly Simon, as well as albums for Sha Na Na and Peter Frampton, and also engineering albums for Lena Horne, Dionne Warwick, and David Bowie, David Live and Young Americans. (The latter featured rhythm guitar from John Lennon on its Number One hit, "Fame".) In 1971 he mixed Humble Pie's double album Performance Rockin' the Fillmore, featuring Steve Marriott and Peter Frampton, still Larry Corryell's Barefoot Boy, his first and only album for Flying Dutchman label, and Curtis Mayfield's double album Curtis/Live!, his first release after leaving The Impressions.
