The Who guitarist Pete Townshend has unveiled the details surrounding his long-awaited remastered 'Quardrophenia' box set, and there's plenty to take in for long-time fans of the band. In addition to the original double album, Townshend has added 25 demo tracks including songs not included on the beloved 1973 album.

"The time has come for me and my team to honour ‘Quadrophenia’ with a carefully presented package that features examples of the impact surround sound (quadrophonic) would have on the music, to remaster the vinyl mixes, and to collect and restore my demos," Townshend said in a press release. "I am also going to try to shed some light on the way ‘Quadrophenia’ came about, and how it was inspired by events in my life in 1970 and 1971, when I scribbled or typed the very first notes and lyrics for some of the songs that made it onto the final record."

A 100-page hardcover book will shed some light on the 'Jimmy' character the album follows through mid-'60s Britain. The press release also promises Townshend's revealing diary from the studio, handwritten lyrics, personal notes and photographs the guitarist recently uncovered.

"The Who, and Jimmy as a kind of model for one or all of our fans, really had developed a powerful symbiosis that deserved a project like 'Quadrophenia' both to honour the mechanism and address why it started to fail almost a soon as it had begun," Townshend wrote in June. The only details missing are the price, which promises to be hefty, and the release date. TheSecondDisc.com is reporting the box set will be available in the U.K. on Nov. 14.
