The sad reality that is groups that only have one thing out.
I'll start with a couple
Stardust - https://www.youtube.com/watch?v=TUC2b-OSZ00
Les Petits Frères de l'Océan Indien - http://www.official.fm/tracks/iMPe
Here is a better quality version.
Well this thread's subject matter is sadly pretty narrow, Stardust is the only band I can really think of that only released a single track. But hey it is a pretty God-tier track for its genre. But most of Thomas' non daft punk stuff like Roule is far better than daft punk IMO.
Awww shit I remember finding this song a few years ago when I was going through all of Thomas' solo stuff and I swear I must have listened to this at least 500 times. Fucking great shit.
I'm of the opinion that Guy-Man is a bit better based of the awesome stuff he did as Le Knight Club. Here's a listen to the short-lived record label he had: https://www.youtube.com/watch?v=M_nNIxfYLU4
I remember there being a torrent with the Daft Punk discography that included both member's solo stuff. Totally worth seeking out
