Stars - changes, 2010

"Montreal's Stars make a very different sound to the euphoric, genre-colliding racket of the members' other group, Broken Social Scene. Their fifth album typifies Stars' more epic melodrama – in awe of Prefab Sprout, New Order and the 1980s to the point where you can imagine videos featuring moody-looking types staring over windswept beaches, pondering Russian novels and their spots. It's all absurdly pretty. Torquil Campbell and Amy Millan's conversational vocals recall Sprout's Paddy McAloon and Dubstar's Sarah Blackwood respectively. However, with every synthesiser airbrushed to an AOR sheen things start to sound bland. Two sounds leap out from the wash of melancholy blue. We Don't Want Your Body is an unlikely tale of druggy vampires and knocking shops in Oxford Street set to harpsichord, featuring the improbable line: "You sold me some cheap Ecstasy, so you could have some sex with me". Changes – with Millan's voice at its sweetest – is simply unutterably lovely."

Black Sabbath - changes, 1972

"Changes" was not recorded with a real string ensemble. Instead, Geezer Butler and Tony Iommi used a Mellotron to create the sound of an orchestra. The ballad is generally an outlier in the band’s discography as it does not feature guitar or drums. To alleviate concerns about the band departing their well-known heavy sound, Osbourne promised in a 1972 interview "We're certainly not going to get any less heavy, we will probably do 'Changes' on stage with a Mellotron, but we'll never take strings on stage with us or anything like that."
