The former Red Hot Chili Peppers guitarist Jack Sherman has died at the age of 64. The band confirmed the news in a statement on Twitter, saying:

“We of the RHCP family would like to wish Jack Sherman smooth sailing into the worlds beyond, for he has passed. Jack played on our debut album as well as our first tour of the USA.”

The cause of death has not been disclosed.

Sherman was the second of at least eight guitarists with the chart-topping band over the years. He played on “Red Hot Chili Peppers” in 1984, toured, and co-wrote some songs for the follow-up, “Freaky Styley.” Although by the time the album was recorded Slovak had returned to the band.

Sherman also contributed to the Abbey Road EP and to the band’s breakthrough release Mother’s Milk, singing backing vocals on Good Time Boys and Higher Ground, but the relationship with his bandmates was never plain sailing, and when the Red Hot Chili Peppers entered the Rock Hall Of Fame in 2012, Sherman was nowhere to be seen.
