Deprecated is a brutal death metal band from USA. The members are still together, however, a lot have other projects. Derek filled in on bass for the recording of Decrepit Birth's "And Time Begins" before joining Suffocation as their full time bassist. A.J. became the vocalist for Disgorge (US) and later Defeated Sanity (Germany). Matt was always Decrepit Birth first and foremost. He rehearsed with Deprecated for 2 months in late 1999.
