This two-man Manchester supergroup--New Order's Bernard Sumner and the Smith's Johnny Marr--made one of the best debuts of the '90s with Electronic. More New Order than Smiths, the album was a blend of plangent fretwork and frenetic sequencing, with bleak lyrics intoned in Sumner's clean, boyish tenor. "Get the Message" was orthodox '80s pop, but the heartbreaking "Gangster" was an electro-rock masterpiece. The album featured engaging cameos from the Pet Shop Boys on "Getting Away with It" and "The Patience of a Saint". --Barney Hoskyns
