Heard a remix on a magazine cover mixtape, tracked down the original. Should have bought the whole album then, which I have since done. The change in tone from the big beefy beaty beginning and the floating midsection gets me right there.
Big beat (ugh, remember that?), reverbed pulses, extra-crunchy acid, and a breathtakingly peaceful middle section (taken from another track on the album, and stretched to full track length in the remix by Spiritualized (Electric Mainline).
