Sabbat were an English thrash metal band from Nottingham consisting of Martin Walkyier (vocals), Andy Sneap (guitars), Simon Jones (guitars), Frazer Craske (bass) and Simon Negus (drums). They are considered one of the "big four" of British thrash metal along with Acid Reign, Onslaught and Xentrix, who were all responsible for developing and popularizing the country's thrash metal scene in the late 1980s and early 1990s. Over their initial six-year run Sabbat released three studio albums, four demos, two split singles/compilation albums, two singles and a live VHS. In 1988, the band released their debut album History of a Time to Come, which earned them further recognition. Their next album, Dreamweaver (1989), was also critically acclaimed. Shortly after the release of Mourning Has Broken (1991), tensions with the band began to surface, most of them revolved around money and Sabbat disbanded as a result. After an attempted reunion in 2001 which was blocked by Sneap, the original Sabbat lineup reunited in 2006. In December of that year they performed together for the first time in sixteen years at five different venues in England. One was a warm-up gig in Nottingham, the other four in support of Cradle of Filth. The band has continued to perform live around the world but has not released any new material. In a January 2014 interview with Decibel magazine Andy Sneap confirmed that Sabbat had once again split-up.

Andy Sneap is an English guitarist, record producer and composer with over 100 albums to his name, most of which have been produced at his Backstage Recording studios in rural Derbyshire. Some of the most critically acclaimed production work on albums include Deliverance by Opeth and Disarm the Descent by Killswitch Engage; for which he earned a Swedish Grammis and a US Grammy nomination, respectively. As a performer, he first built his reputation as one of the guitarists in the British thrash metal band Sabbat, and played with them up until their disbanding. He is currently one of the co-guitarists of the British heavy metal band Hell. In 2018, Sneap joined Judas Priest as a touring guitarist, following long-time lead guitarist Glenn Tipton's diagnosis of Parkinson's disease which conflicts with his touring abilities, and while not an official member of the band, he contributed guitar work to their nineteenth studio album Invincible Shield (2024).
