> from "Mike's Song" (in a show that would, ultimately, become a "Groove") slinky play emerges as the lyrics fade, the band riding a wonderfully-paced, feel-good wave.

Check out Page, around the ten-minute mark, as he shakes things up, via his concert grand, a really cool passage that Trey responds to in kind. Page shifts to his keys, and play becomes refreshingly rocking, with a set of repeated riffs that are as pleasant as the surf smacking the shore. Trey breaks free, working the version to a strong peak before play uniquely cools to a perfectly placed "Ya Mar."
