J Mann was one of the lead vocalists for Mushroomhead. He was the vocalist that did the "rapping" parts of the songs. He is awesome and if you don't think so, then you don't know "cool" if it ran up and started crying that you copied his band. Oh, that is Correy Taylor from Slipknot, not "cool", my mistake...

Jason Popson,or J Mann, was a kick ass member of Mushroomhead. He had the unique white face paint with the black around the eyes. The other member's masks at the time were oriented around black, so he normally stood out in the group. He has has been in many side projects other than Mushroomhead, but 216 is probably the biggest.. Some say J Mann screamed too much. I say, you whine too much. Don't complain about J Mann and go kill yourselves. Now the band uses blood white costumes and Waylon has replaced J Mann because he quit...

All in all, J Mann is freakin' sweet, and if you disagree, then you are freakin' gay.
