Boss Keloid are a progressive / sludge metal band from Wigan, England. The band was formed in 2010 by Paul Swarbrick (guitar) and Alex Hurst (vocals) over their “shared love of riffs and interesting music”. Ste Arands (drums) joined in 2011 just before they starting writing their first album ‘The Calming Influence of Teeth’ and Adam Swarbrick (bass guitar) joined in 2014 halfway through the writing on the album ‘Herb Your Enthusiasm’.

They derived their name from an Iron Monkey song, however their sounds differ.
