The opening track "If We're in Love" is a downtempo song featuring a boogieswing rhythm and sharp brass parts, opening with phased vocals and closing with a call and response between brass and keyboard parts.[2] Following "Sinking Feeling", which uses a beat constructed from clicking sounds,[3] is "Ramalama (Bang Bang)", which contains a chorus of onomatopoeic lyrics[3] delivered over a tribal rhythm.[4] The extended play closes with "The Closing of the Doors", a cabaret-style ballad driven by the piano.[3]
Cover artwork
The cover of Sequins 3 was painted by Simon Henwood. Murphy met Henwood in a pub, and Henwood, who was known for his simplified paintings of teenagers, thought that she would be a good subject for a painting.[5][6] Henwood came to Murphy's house the next week and, while they were looking through her wardrobe, decided to have her dressed in sequins.[5] Murphy positioned her body in abstract shapes for Henwood to paint.[6] She developed a character, which Henwood described as a "disco electro pop diva with a 1940s look".[7] His canvases were displayed at The Hospital in Victoria, London,[8] and Murphy purchased them "for [her] kids so they can see what [she] once looked like."[6]
