Drummer with Primus.

Alexander and Les Claypool first met at the Berklee School For Music in Boston.

He first appeared on Primus' live album Suck On This, which included a drum solo featuring Alexander's double bass drum technique. He also appeared on their studio albums Frizzle Fry, Sailing The Seas Of Cheese and Pork Soda.

After the tour in support of the last of these, Alexander and Primus took a break, during which time he started a band with his own friends called Laundry.

After the break, Primus recorded Tales From The Punchbowl. After the tour for this album, he left the band and continued playing with Laundry, but is now reported to be back with Primus.
