Smoke on the Water

Almost everyone who has picked up a guitar has played this riff within their first year — four notes descending, repeated in three keys, and yet it still carries the weight of the moment it was born from. The song is built around one of rock's most famous accidents: a keyboard malfunction in a Montreux casino, a fire that swept the venue, purple smoke rising over Lake Geneva. The production captures a live-band tightness, a sense of musicians who had been playing together long enough to trust the space between notes. Ritchie Blackmore's guitar is precise and muscular without being showy, and Ian Gillan's voice rides above it all with an ease that disguises how much control it requires. The song is ultimately about witnessing — describing what was seen, what was lost — and that documentary impulse gives it a peculiar emotional honesty. It belongs to the early 1970s British hard rock scene that also produced Led Zeppelin and Black Sabbath but had its own more technically proficient character. You don't reach for this one in a state of feeling — you reach for it when you want the feeling of being in a room with a great band that is completely locked in, when craft and momentum are what you need.
