          Tumma traveled to San Jose, CA to recruit for his DJ crew [FURFORCE] back in early 2011. This ended up deveoping into an exclusive content record label within the furry community releasing 2 albums and 6 EPs within the year and gaining sponsorships with KittyLovesMonster.com as well as street team sponsorship from Monster Energy and V-Moda. 2012 started off with filming a [FURFORCE] Documentary includining shows in San Jose, CA - Atlanta, GA - Reno, Nevada - Cromwell, CT - and many more. Durring a month of downtime, the record label went on an unexpected hiatus and is still on break to this day. The documentary was stopped and put on hold as the shows continued for the year.
