Christabelle Sandoo is a nomad diva who landed in the Oslo studio of Hans-Peter Lindstrom, the electronic producer whose 28-minute 2008 "Where You Go I Go Too" posited a new genre: epic prog-house. They're a perfect pair. Christabelle maximizes her limited instrument throughout, speaking with moist vowels between sung verses like Grace Jones in a training corset. Lindstrom's tracks shine like sun on snow, disco struts alternating with electro-funk chugs. Defining moment: a techno-fied cover of "Let It Happen" by Vangelis, another visionary European who never let genre considerations get in the way of a tasty overproduction.

“Everyday People”

"Everyday People" managed to trailblaze in two different ways -- it was one of the first pop hits to deal with the subject of racial harmony, and it utilized Larry Graham's "slap" technique on the bass guitar, which would soon be copied by countless other bassists. Graham once said about his pulsating style, "I'd never done that before … that's where the freedom of creativity came in for the band, that we'd be allowed to do that." In 1978, the song's line "Different strokes for different folks" would be borrowed for the title of the hit television show Diff'rent Strokes.
