In 1968, after living in London for two years, the guitarist needed a new flat. Twenty-three Brook Street, in Mayfair, took Jimi Hendrix’s fancy, not least for the blue plaque at number 25, where George Frideric Handel had lived. It opened to the public on Wednesday, as part of a space called Handel & Hendrix in London. For years it was used as offices: the bedroom he shared with his girlfriend has been recreated from old photographs (only a mirror is original). Hendrix fans will nonetheless be tickled to see that lived more like a university student—rent of £30 (then $72) a week, rugs from the nearby John Lewis department store, acoustic guitar, ashtrays—than like one of rock’s brightest-burning stars at his peak. Among the few pricey items are the Bang & Olufsen turntable and Lowther speakers on which Hendrix listened to the blues, his contemporaries—and a few works by Handel.
