Pig Destroyer have released a two-song digital EP via Bandcamp, titled Mass & Volume. The songs-- the title track, and a song called "Red Tar"-- come from the sessions for Phantom Limb. Proceeds from sales of the EP will go toward the college fund for Pat Egan's daughter. Egan worked for many years with Relapse Records before passing away last month. The band writes:

Pat Egan was a friend and a keystone member of the Relapse family for many of the years we have been involved with it. He devoted his life to supporting underground music and he immeasurably helped develop the bands he worked with. His untimely passing on February 18 2013 shocked the many people that his life and work had touched. This EP is dedicated to the memory Of Pat Egan and to the loving family he left behind. RIP Pat.
