David Gilmour's guitar solo on Money is played over a 7/4 time signature — one of the most unusual rhythmic contexts for a rock guitar solo — and Gilmour navigates it with complete naturalness, phrasing across the odd meter as if it were perfectly ordinary. The solo is aggressive and bluesy compared to Gilmour's more atmospheric work, showcasing a rawness that his reputation for restraint sometimes obscures.
