I feel like in the club/dance music world, a lot of DJs are producers. Like if you look at who headlines the big festivals most of them are known for making great tracks.
Exceptions are the older school guys, and people who began as straight DJs and shifted to doing producing but still go by their DJ name vs rebranding.
Theres a lot of practicalities that make doing live producer type sets at shows a headache. It seems like a lot of producers play sets with stems or loops off cdjs (at least the ones I like and watch their sets).
Personally, for this type of music I’d rather listen to a good dj or producer make something in the moment layering pre-produced loops, either from their own tracks or others. In my view thats just as musically valid as doing a live performance with several instrumentalists and a singer, and as a punter it gives a more enjoyable experience.
But stuff like say Nils Frahm, Christian Löffler, Rival Consoles etc its not necessarily music you doof out too and lends itself more to like a seated appreciation type of setting, with live recreation with key parts performed live.
Like if a “dj” is playing music in a club, but what people are hearing is actually 4 loops from 4 different tracks layered over each other, thats just a form of music performance that wasn’t possible or feasibly until relatively recently.
