A great ska band influenced by Elvis Costello (who produced their first album in 1979) and who loved the chaotic dance-party shows.

The Specials, also known as The Special AKA, are an English 2 Tone and ska revival band formed in 1977 in Coventry. Their music combines a “danceable ska and rocksteady beat with punk’s energy and attitude”, and had a “more focused and informed political and social stance” than other ska groups. The band wore mod-style “1960s period rude boy outfits (pork pie hats, tonic and mohair suits, and loafers).”
