From WarTape's Twitter:
"Check out this month's issue of Modern Drummer Magazine! William is featured in an article with Jimmy Chamberlin!!! Page 34!!! Xo"
Confirmed by the publication itself:
"Drummer to Drummer: Jimmy Chamberlin (Smashing Pumpkins/Jimmy Chamberlin Complex) and William Mohler (War Tapes) interview each other."
Thanks for the heads up Lifebeginsagain37
