In a situation that can really only be described as unique, Primus’ Tim “Herb” Alexander left the band by email.

The band’s social media post reveals the drummer emailed them on Oct. 17 “expressing that effective immediately he would no longer be involved with Primus.”

Primus’ reaction is posted below:

“On the heels of a wonderful Spring & Summer of touring and some fabulous plans ahead, it has been a bit bewildering for us that Herb would so abruptly opt out,” the band said in a statement. “After several attempts to communicate with Herb, his only response was another email stating that he has ‘lost his passion for playing.’ As disappointing as that is, we respect his choice and it’s forced us to make some tough decisions.

“We’ve considered cancelling the annual New Year’s show, but after much talk Les and Ler have decided to pivot to an augmented version of Primus featuring members of Holy Mackerel and Frog Brigade. This will be an exciting special, one-time event. As far as future Primus, the band is looking forward to performing in the Dominican Republic with Tool and others. Danny Carey has once again graciously offered to fill the drum throne. For Sessanta, Primus plans on searching for the ‘greatest drummer on earth.’”

Primus, which doesn’t plan on canceling any shows, was formed in 1984.
