Chapman and Blondie also used plenty of other little tricks on “Heart Of Glass”: digital reverb, multi-tracked guitars, echo machines, a Minimoog, Chapman’s own backing vocals. It’s a beautiful piece of recording, all these sticky and hazy interlocking pieces combining together into a sighing, rippling landscape. Parts of it — Clem Burke’s lockstep drums, Nigel Harrison’s funky and vaguely Chic-esque bass-pops — sound truly disco.
