That’s one of my favorite images of Robert Fripp. Lately I’ve been listening rather obsessively to a relatively neglected track from Eno’s masterful Another Green World, “St. Elmo’s Fire.” Eno had asked Fripp to come up with an aural equivalent of the dance of St. Elmo’s fire among the masts of a ship — and I’ll be rubbished if he didn’t do exactly that. Technically brilliant, yes, but, more, so wonderfully imaginative.
