According to NME.com, METALLICA and BLACK SABBATH will team up for a special one-off joint 12-inch vinyl single to celebrate 'Record Store Day' (April 17).

Limited to just 1,000 copies, the release - with each band logo on a corresponding side of the record - features the UNKLE remix of METALLICA's "Frantic" and a version of BLACK SABBATH's "Paranoid" with alternate lyrics.

'Record Store Day' celebrates the continued existence of independent record stores, mostly through live in-store appearances, performances and special limited-edition releases that will only be sold through participating stores on the day itself, which is April 17 this year.
