Arguably Britain's best thrash band ever, Sabbat had quite an original style, owing much to Martin Walkyier's venomous, rapid-fire vocal delivery, and tight, precise, and often-changing riffing. They released two outstanding albums in the late eighties, but friction between various band members started to develop, some of which was centered around Walkyier's continuation of his pagan lyrical themes. Bassist Frazer Craske left, and then so did Walkyier, who went on to form the highly successful Skyclad. A revamped lineup recorded and released Mourning Has Broken in 1991, but this album lacked almost everything that made the first two albums so unique, and thus is often a forgotten part of the Sabbat story. Sensing that their time had past, the band disbanded in the middle of their UK tour soon after the album's release. Sneap later formed a band called Godsend (not the Swedish doom band Godsend), and is now a highly regarded metal record producer, having produced albums by Skinlab, Exodus, and others.

In 2007 Walkyier, having left Skyclad several years prior, settled his differences with his old mates, and the Dreamweavers-era version of the band officially reunited, though bassist Craske has since decided not to continue.

Note: no relation to Sabbat, a Japanese thrash/death metal band.
