Ian McLagan, the legendary keyboardist who was a member of the Small Faces and the Faces, has died. He was 69 years old.

Earlier today, news broke that McLagan, who was also a longtime sideman with the Rolling Stones, was admitted to an Austin hospital in critical condition. According to the Official Small Faces Fan Club, McLagan had a "massive stroke." KXAN in Austin had previously reported that he had a head injury. Paste Magazine has also reported that one of their writers, Tim Basham, was present in the hospital room when McLagan passed away.

McLagan started his career in the early '60s playing with local British groups (one included future King Crimson and Bad Company member Boz Burrell). By 1965, he was a member of the Small Faces, who scored with songs like 'Itchycoo Park' and 'Tin Soldier.'

When Steve Marriott left the band in 1969, singer Rod Stewart and guitarist Ron Wood took his place, and the band renamed itself the Faces. With Stewart at the helm, they recorded such classics as 'Stay With Me' and 'Cindy Incidentally' before breaking up in 1975.

That year, after Wood joined the Rolling Stones, McLagan became an auxiliary member of the group, joining them on tour and occasionally in the studio. His most timeless contribution is the electric piano that rolls through their No. 1 1978 hit ‘Miss You.’

McLagan had played with many rock luminaries over the years, including Chuck Berry, Bob Dylan and Bruce Springsteen. He's also performed with Izzy Stradlin, Paul Westerberg and was a member of Billy Bragg's band. He was most recently on tour with Nick Lowe.

He also fronted his own Bump Band, which was based in Austin, where McLagan has called home for the past several years. Since the late ’70s, he's released nearly a dozen solo albums, including his most recent, 'United States,' which came out in June.

In 2000, McLagan published an autobiography, 'All the Rage: A Riotous Romp Through Rock & Roll History,' which was updated last year. In 2012, he was inducted into the Rock and Roll Hall of Fame with the Small Faces and the Faces.
