The musician, who has worked with a number of high profile musicians over the years, was the guitarist for Chris Robinson Brotherhood and Circles Around the Sun. Only last week, he took to Twitter to announced that he would "be producing a new record for the amazing singer/songwriter Kenny Roby" in the coming weeks.

Casal was a member of Ryan Adams' backing band, the Cardinals, for several years, recording three studio albums. Adams remarked that his "heart is broken" at the news, remembering Casal's "kindness & brotherhood":

Oh man.
My heart is broken
What an honor to have known you, true believer. I love you. Go easy
“I've seen things you people wouldn't believe. I watched C-beams glitter in the dark near the Tannhäuser Gate. All those moments will be lost in time, like tears in rain”#RIPNealCasal pic.twitter.com/4vlj3l2EoU
