As we mentioned on Friday, Pig Destroyer have released a two-song EP from the Phantom Limb sessions, with the proceeds going directly towards the college fund of Pat Egan’s daughter Katie. Beloved by bands, his label, and his friends and family both in and out of the music industry, Egan died on February 18th from pneumonia-related illnesses. Mass and Volume is now on sale at Bandcamp for $10. The EP is divided into two parts, with “Mass” a 19-minute long epic, and “Volume” a more compact 6 and a half minute running time. Here’s what the band had to say about Mass and Volume:

This ep was written and recorded during the final day of the Phantom Limb sessions with unexpected extra studio time and resources. In the following years, with Natasha being released on its own and Brian no longer being in the band, our intentions of releasing Mass & Volume basically evaporated. However, looking back now, Mass & Volume serves as a great epilogue to that particular era of the band.

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.

There won’t be a physical release of the EP. This is the only way to get it, and it’s for a more than worthy cause. You can still pick up the Patlapse compilation for as little as $5, which will also benefit Egan’s daughter. And a memorial/benefit will happen at New York’s Idle Hands Bar tomorrow, with an auction taking place on Ebay as well.
