Castle Music has announced plans to officially reissue the legendary 1977 Sex Pistols bootleg Spunk. Castle Music is an imprint of Sanctuary Music responsible for a number of notable classic punk releases, including box sets from Discharge and GBH.

Spunk was a set of demos recorded by Dave Goodman that captures the band over a year before the release of their groundbreaking debut Never Mind the Bollocks. It features prototypical versions songs from that full length, many bearing different titles. The material from those sessions has shown up on nearly every of the numerous Pistols bootlegs since. Castle's website states:

Never mind the official album, this is the real sound of the Sex Pistols. Back in 1977, the Spunk bootleg captured the authentic aural assault of punk's premier protagonists, more than a year before they released their first legal LP. Spunk has gone down in history as the finest British punk record, and this anniversary edition - available with bonus tracks on CD, or on limited edition vinyl - recaptures all the sonic thrill of the Pistols at their peak.

The reissue arrives in UK record stores today and will be released in North America on August 15th. The CD will include the bonus tracks while the vinyl version is limited to 1000 individually numbered copies.
