What I did was take the FWWM etc. tracks from the Twin Peaks Archive as listed on the soundtrack design site and spliced them together to form a near-complete FWWM playlist (having also recently found a copy of Season Two Music And More off Amazon for a reasonable price, with which I'll be able to complete it). The FWWM tracks from the Archive stand in a separate league of their own, it's true. When you listen to them together like that, you can really hear a precursor to his Lost Highway tracks.
Having not seen Episodes 3 and 4 yet (tonight hopefully!) I'm doing that thing I shouldn't be doing - visiting this thread and scrolling over posts that talk about them.
