Trey still doesn't sound all that tight, unfortunately. His hits aren't that clean. Mike's solo-section is good, but nothing out of the ordinary. Trey plays pretty well in the pre-charge section, though. Trey scats a bit during it.
Page takes off on the keys.
Mike and Trey are clearly on the tramps, given the signals from Mike. It definitely clashes with what Page is doing. Trey starts noodling around at first, but gives up quickly in favor of rhythmic chording. Mike gets more active as a result. But I have no idea what the name of the tune this RIFF is really from.
