Avery has a history with Reznor as he was still part of Jane’s Addiction at the point where the Nine Inch Nails mastermind was attempting to guide them through the recording process of their last album. Reznor did not stick with Jane’s in the studio through the entire process and Avery also split with Jane’s as well before ‘The Great Escape Artist’ disc was complete.
The bassist’s departure appears to be amicable from his statement. His posting reads as follows:
Its with very mixed emotions i tell you all that im pulling out of NIN. i know. its been a tough call and i don’t know if its the right one. but i really want to focus on my musical life here in la, on film work in particular. as the tour dates kept growing… i just got overwhelmed. i just got home from a year of heavy travel with garbage, the idea of leaving town for another year and a half, and with all the intensity that nails demands… fortunately my friend Trent understands all this and appreciated my pulling the plug now instead of deep into 2013 and 14. go get em gentlemen.Nine Inch Nails began rehearsals for their summer shows earlier this month. They’re currently scheduled to headline Outside Lands, the Voodoo Music + Arts Experience, the Made in America festival and Lollapalooza among their festival dates around the world this year.
