Basically trip hop for people who missed out on or are too young for trip hop.
Nujabes, Massive Attack, Portishead, Unkle, Little Dragon, and many more great artists/bands that all have produced albums and songs that could be described as lofi, often find their work in lofi mixes.
I think this is pretty smart, the original probably isn’t getting more popular, just the same people who’ve stayed caught up over the years, I’ve tried starting it, but that many episodes is quite daunting. Personally I’m much more likely to watch this as it comes out.
