Jason Costa: "I love playing fast double bass, and barefoot, I can feel the complicated patterns." With Diecast member Jonathon Kita, Jason Costa founded a side project band in 2002.
In November 2005 Jason Costa left the band. Early 2006 Diecast added drummer Dennis Pavia to their line-up.
Next Jason Costa joined Massachusetts metallers All That Remains.
