Aaron Rossi played drums in Shelter, Strife, and Ankla among others. His first tour was when he was 20, with Shelter. Recalls Aaron: "They were on Century Media Records at the time. I didnít know who they were when I joined. But when we went to Europe, we were playing shows in front of 30,000 people, so I was really excited about that. And then I came home and joined another hardcore band, Strife, and went back out to Europe again."
In September 2005 Rossi joined Prong.
Despite the many rumours Aaron Rossi never played with Medication; he did audition for them though. After the audition, he ended up recording a demo with Logan Mader (ex-Medication, Machine Head, Soulfly).
More recently Aaron Rossi has been drumming for Al Jourgensen's band Ministry, and Black Oil.
The Grammy nominated drummer (for Best Metal Performance: Ministry's Senor Peligro off the album 'Adios... Puta Madres') has also started his own group called Sizematic.
