Mountain guitarist and co-founder Leslie West has died.
The band dropped the sad news ... "With a heavy heart, we are saddened to hear about the passing of #Dean Artist and part of the Dean family, Leslie West. [He was] legendary and one of a kind. Rest In Peace."
Leslie went into cardiac arrest at his Florida home and died Monday.
In '69, Leslie co-founded Mountain. The group's big break was performing at Woodstock their first year as a band, and it instantly cemented their status.
He's best known for his vocals on the song "Mississippi Queen."
Here's how Leslie described "Mississippi Queen" ... "[it] had just everything you need to make it a winner. You’ve got the cowbell, the riff is pretty damn good, and it sounds incredible. It feels like it wants to jump out of your car radio. To me, it sounds like a big, thick milkshake. It’s rich and chocolatey. Who doesn’t love that?”
Leslie had his health struggles. His leg was amputated in 2011 ... the result of complications from diabetes.
