Prog rock is lambasted for its bombast and excess, but at its best restraint is its true hallmark, along with an ability to lock into a groove and do it to death as much as any of the funk bands that were the monsters of prog’s contemporaries during their mutual heyday. One of my all-time favorite classic-rock radio jams — it counts as one, since like “Sgt. Pepper’s (Reprise)/A Day in the Life” or “Time/Breathe (Reprise)” or what have you its two halves segue together and are never played separately — the combo better known simply as “Long Distance Runaround” puts both qualities on ample display. The first half is all about holding back: After faking us out with a squiggly guitar filigree and rhythm-section churn, the song settles down into a main section characterized by a softly jaunty keyboard part, complemented by the broken-up phrases and clipped delivery of Jon Anderson’s vocals and a joint guitar/bass line from Steve Howe and Chris Squire that drops in a few notes every so often and then cuts off almost as soon as it begins. It’s a restrained approach well suited to Anderson’s lyrics, which sing of the frustration of opportunities squandered and expectations never met, and it creates a refreshing amount of space around each instrument, if that makes sense — you feel present in a room with various musicians contributing every so often, then holding back, content to let things linger in the air. Lyrically, the second half of the song may consist only of nonsense — the taxonomic name of a fish chanted as though it contained the secrets of the universe — but the instrumentation seems to house all the angst lurking beneath the pinched and placid surface of the first half. Essentially a drum and bass duet with Squire overdubbing a rather extraordinary range of approaches to his instrument and future King Crimson behemoth Bill Bruford providing a tight percussion backdrop, it seizes a 7/4 rhythm and exploits it, introducing new and increasingly menacing bass elements every few turns of the screw. It’s difficult for me to hear it and not nod my head along, leaning into the music as it barrels forward.

I’ve probably listened to this song more often after catching it by chance while flipping around my car radio presets than on my iPod, and in that context it shines even brighter, I’d say. Music on the radio often comes through as a wall of noise, filling every available sonic space, sounding emitted rather than performed and recorded. “Long Distance Runaround”‘s dynamics give my ears empty spaces to dart into, and I can “see” the rest of the music from that vantage point as it plays, instead of merely sitting there and letting it blast over me.
