Alexander, who also drums for Puscifer, suffered a heart attack late last week
"The Mighty Tim 'Herb' Alexander has pulled through surgery, the blockage from his heart has been removed with no complications and all signs point to a glorious and speedy recovery," the post read.
Prior to Monday's surgery, Alexander's family released a statement, asking fans to keep the drumbeat going during the procedure. "The heart is like a drum and we need to help keep it going, so during this time we ask you to please help carry that beat," the statement reads. "Whether it be drums, percussion or even in your head, we would like to start a global drum circle to send positive, healing energy to Tim."
In addition to his on-and-off gig with Primus since 1988, Alexander has also worked with Maynard James Keenan, drumming for Puscifer and A Perfect Circle, as well as the Blue Man Group in Las Vegas.
