Porcaro had been suffering from amyotrophic lateral sclerosis

Mike Porcaro, Toto‘s long-time bass player, has died. He was 59.

As reported by Rolling Stone, Pocaro passed away earlier today (March 15) following a battle with amyotrophic lateral sclerosis, commonly known as Lou Gehrig’s Disease. The news was confirmed by the band’s keyboardist and Porcaro’s brother, Steve, via Facebook.

“Our brother Mike passed away peacefully in his sleep at 12:04 AM last night at home surrounded by his family,” he posted. “Rest in peace, my brother.”

Porcaro joined his brothers Steve and Jeff (who died in 1992) as a member of Toto in 1984, going on to play on the hits ‘Rosanna’ and ‘Africa’. He stopped touring in the mid-2000s due to declining health, but was inducted into the Musician’s Hall of Fame alongside the band in 2009.
