Leslie West Dead Due To Cardiac Arrest

The sad news was confirmed by his brother Larry West Weinstein to Rolling Stone, stating that earlier this week, the legendary frontman suffered cardiac arrest at his Daytona, Florida home.

He was immediately rushed to the hospital but never regained consciousness.

Moreover, blabbermouth.net cited that prior to his death, Leslie was in a critical condition after his heart stopped and had to be put on a ventilator.

In a now-deleted post, West's brother asked everyone for their prayers.

"I am asking for all your prayers. [Leslie's wife] Jenni is by his side in Florida but it's not looking good. Thanks Jenni, he wouldn't have made it this far without you. His heart gave out and he's on a ventilator. May not make it through the night."

Following Leslie West's death, fellow musicians and fans paid their respect.

Swedish guitarist and founding member of Arch Enemy, Michael Amott, paid a tribute for his passing and shared that he is a "big influence" in the music industry.

"Rest in Power #LeslieWest! I love his playing, singing and writing. A big influence on so many musicians, including myself. Leslie had THE SOUND in his hands. Was so cool to hang out with him at a NAMM dinner in '09, what a great friendly guy and phenomenal musician. R.I.P."

In 1970, Mountain reached the peak of their career, thanks to their chart-topping song "Mississippi Queen."

In his previous interview with Guitar Player in 2019, West mentioned that the guitar banging rock song "has just everything you need to make it a winner."

Moreover, he even compared his song to a "thick milkshake" with its "rich and chocolatey" taste that everyone can't resist.
