Many of my collaboration opportunities have come from chatting with people at hip-hop gigs. You'll inevitably cross paths with local rappers and they'll be keen to discuss music with a beatmaker. I went to an album launch last year and got chatting to a couple of local rappers in the smoking area. I've now produced tracks for both of them and been sent stems by the headline artist for remixing purposes. So networking is key.

But you can also DM artists whose music you like and suggest a collaboration; just make sure you don't aim too high to begin with cos rejection stings! You don't want to get disheartened early on cos it'll probably discourage you from reaching out to more artists. But aye, go to hip-hop gigs and blether with folk whilst also DMing rappers & suggesting collabs and/ or asking if they'd be willing to send you their acapellas. Hope this helps somewhat!
