Learning to put together live streams, green screens and graphics - it’s canny hard to do it well on your own!
(and chat to everyone, and make sure everything is working, and select tunes, and mix, etc). It’s just way more to do than DJing but he’s one of the people I respect for adapting well.
I know a lot of solid DJs who are shying away from it because they aren’t feeling confident or nobody can support their weaknesses in technology.
