IN: Led Zeppelin is the eponymous debut studio album by English rock band Led Zeppelin. It was first released on 12 January 1969 in the United States and on 31 March 1969 in the United Kingdom by Atlantic Records. Featuring integral contributions from each of the group's four members, the album was recorded in October 1968 at Olympic Studios in London, and established their fusion style of both blues and rock music. It also attracted a large and devoted following to the band; Zeppelin's take on the emerging hard rock sound endeared them to parts of the counterculture on both sides of the Atlantic Ocean.

Led Zeppelin was produced by Jimmy Page and engineered by Glyn Johns, both of whom had known each other since teenagers in the suburb of Epsom. According to Page, "The first album is a live album, it really is, and it's done intentionally in that way. It's got overdubs on it, but the original tracks are live."  Page reportedly used natural room ambience to enhance the reverb and recording texture on the record, demonstrating the innovations in sound recording he had learned during his session days. Up until the late 1960s, most music producers placed microphones directly in front of the amplifiers and drums. For Led Zeppelin, Page developed the idea of placing an additional microphone some distance from the amplifier (as far as twenty feet) and then recording the balance between the two. By adopting this "distance equals depth" technique, Page became one of the first producers to record a band's "ambient sound": the distance of a note's time-lag from one end of the room to the other.  Another notable feature of the album was the "leakage" on the recordings of Plant's vocals. In a 1998 Guitar World interview, Page stated that "Robert's voice was extremely powerful and, as a result, would get on some of the other tracks. But oddly, the leakage sounds intentional." On "You Shook Me", Page used the "backward echo" technique. It involves hearing the echo before the main sound (instead of after it), and is achieved by turning the tape over and recording the echo on a spare track, then turning the tape back over again to get the echo preceding the signal.  The album was one of the first albums to be released in stereo-only form; at the time, the practice of releasing both mono and stereo versions was the norm.

input: In May 1971, the Temptations finally found a permanent replacement for the first tenor position in twenty-year-old Baltimore native Damon Harris. Otis Williams, Edwards, Franklin, Street, and Harris continued recording and performing, and Norman Whitfield continued producing hits for them. There were Top 40 hits such as "Superstar (Remember How You Got Where You Are)" (1971), a message from the Temptations to David Ruffin and Eddie Kendricks, and "Take a Look Around" (1972). During this period, the group toured with Quiet Elegance as their back-up singers. Quiet Elegance featured Lois Reeves, the sister of Martha Reeves, alongside Frankie Gearing and Millie Vaney-Scott.  Late 1972 saw the release of "Papa Was a Rollin' Stone", a magnum opus written by Norman Whitfield and Barrett Strong and produced by Whitfield. Originally a three-minute record written and produced for the Undisputed Truth, Whitfield took the somber tune and created a sprawling, dramatic twelve-minute version for the Temptations--a forerunner of the extended single, soon to become popular in clubs and discotheques. An edited seven-minute version was released as a single and became one of the longest hit singles in music history: it hit number 1 on the pop charts and number 5 on the R&B charts. In 1973, "Papa Was a Rollin' Stone" won the Temptations their second Grammy for Best R&B Performance by a Group. Whitfield and arranger/conductor Paul Riser won the award for Best R&B Instrumental Performance for the instrumental version on the B-side, and Whitfield and Barrett Strong won the songwriting Grammy for Best R&B Song.  After "Papa Was a Rollin' Stone", Whitfield stopped working with Barrett Strong, and began writing the Temptations' material on his own. The success of "Papa" led Whitfield to create more elongated, operatic pieces, including the Top 10 hit "Masterpiece" (1973) and several of the tracks on the resulting Masterpiece album. Tensions developed between Whitfield and the group, who found Whitfield arrogant and difficult to work with, and the group citing his habitual tardiness, his emphasis of the instrumental tracks at the expense of their vocals on many of his productions, and the declining singles and albums sales as other sources of conflict, sought to change producers. Otis Williams complained about Whitfield's actions and the Temptations' stagnant sales to Berry Gordy; as a result, the group was reassigned to Jeffrey Bowen, co-producer of the 1967 In a Mellow Mood album.  The final Norman Whitfield-produced Temptations album, 1990, was released in December 1973, and included the Top 30 single "Let Your Hair Down". Shortly afterwards, Whitfield left Motown, and in 1975 established Whitfield Records, taking the Undisputed Truth and Willie Hutch with him, along with Rose Royce---who performed an instrumental track for "Let Your Hair Down" before recording their 1976 smash "Car Wash."
