It's often been said that a mind unlocked by psychedelics is better equipped to perceive simple truths. The Beatles' cure for an LSD-induced hangover was a return to rock 'n roll ("Lady Madonna"), while Bob Dylan re-emerged with an album of country songs. The Rolling Stones also started work on a new album within this back-to-basics framework, with new producer Jimmy Miller in control.
Songs were worked on prior to the sessions, and time, plus a grim determination to put the musical uncertainties of the past eighteen months behind them, all contributed to a new mood of optimism. And with Andrew Oldham out of the picture, and Brian Jones slowly but unquestionably fading, the Jagger-Richards partnership had become absolutely central to the quest.
March 1968 The Stones, except for Brian Jones, but with Ian Stewart in tow, started rehearsals for the forthcoming new album in the small, but familiar R.G. Jones Studio, Morden, Surrey. "I'll Coming Home" is a fine example of the energetic jam sessions, during which many songs were worked on for the first time. It's pretty clear that the band intended to shift their style back to the blues, with a harder rock edge and feel.
