Mike Musburger joined The Posies in April 1988. He left in July 1994, but played with Ken, Jon, and Joe Bass as the Posies on 22 September 1999.



Mike Musburger's reason for leaving, according to Durkin's Posies bio: "Mike was unhappy; since he didn't tell the rest of the band, it created a tension that no one could really identify. Since Jon and Ken had been getting so much attention, he felt slighted, as if his contribution wasn't being recognized. Things finally came to a head when Mike and Ken got into a big fight, which resulted in Mike's departure from the band. "At the time," Ken remembers, "he said that it was because of the fight and because of me. Later, he admitted that maybe he'd been waiting for something like that for a long time."



Mike Musburger was followed up by Brian Young.



Musburger also recorded with Bicycle, Capping Day, Damien Jurado, Fastbacks, John Wesley Harding, Love Battery, Makers, Marshall Artist, Screaming Santas, Shuggie, Skyward, Super Deluxe, Tales from the Birdbath, The Squirrels, Trachtenburg Family Slideshow, Tube Top and Tuffy. He was drum technician for the Supersuckers.
