   Mike and Rebecca started doing sound effects (foley) in 2005 for various theater productions of old time radio shows. 

   Through the years, they continued to study the art of foley and assembled enough sound effects to cover two six-foot tables, as seen in their regular performances of "War Of the Worlds." 

SRDXFX is an abbreviation of their last name (Suerdieck) + FX (short for Sound Effects.)
