Ten Years After singer and guitarist Alvin Lee died Wednesday after complications during a routine surgery.

Lee's personal website, alvinlee.com reported the death of the 68-year-old vocalist and guitarist.

"With great sadness, we have to announce that Alvin unexpectedly passed away early this morning after unforeseen complications following a routine surgical procedure," Jazmin, Evi and Suzanne of Lee's family wrote on the site.

Born Graham Alvin Barnes, Alvin Lee and Ten Years After made their claim to fame when the band performed at the Woodstock festival in 1969.

The band faced technical issues during their set, but a 12-minute encore rendition of "I'm Going Home" filmed for the documentary "Woodstock," went on to become an iconic rock performance.

"We have lost a wonderful, much-loved father and companion," Lee's family wrote on the site. "The world has lost a truly great and gifted musician."

Ten Years After's string of hits included "I'm Going Home," "I'd Love To Change The World," and "Love Like A Man," all songs driven by Lee's fluid lead guitar playing.

The legendary guitarist would leave the band a few times before pursuing a solo career in 2003.

Alvin Lee's final recorded album, "Still on the Road to Freedom" was released late August. The final track on the album is titled, "Love Like A Man 2," which is a sequel to one Ten Years After's biggest hits.
