Before Daft Punk, Thomas and Guy-man were part of a group called Darlin’ (Darlin' (French band) - Wikipedia) with Laurent Brancowitz, who would go on to be a member of the band Phoenix. The group only made 4 tracks (Darlin' (Full Discography) - YouTube).
Daft Punk got their name when British music magazine Melody Maker called the music by Darlin’ “daft punky thrash”.
Because of their history, Daft Punk performed live alongside Phoenix at Madison Square Garden (Phoenix and Daft Punk - 1901 - Madison Square Garden - YouTube)
