I just wanted to drop a quick note that Darren re-issued Under the Flightpath earlier this year. It's not strictly the same, he slowed down the BPM a tad.

He also re-issued some Cliffhanger tracks:

And he also released "The NovaMute Outtakes" which is all unreleased tracks. The Underworld-adjacent connection is that "Step to the Groove" was played on the Underworld radio show for the Oblivion Ball.
