https://en.wikipedia.org/wiki/Lo-fi_music "In the late 2010s, a form of downtempo music tagged as "lo-fi hip hop" or "chillhop" became popular among YouTube music streamers. Several of these channels attracted millions of followers."
Members' ages will be late 40's to early 50's. Going their own way and ignoring trends. Their song is like a lottery, but its rough beat is the great attraction.
There are some excellent producers in the group. One of them, Showbiz has a good ear. He creates beats with very characteristic samples.
Lord Finesse is both producer and MC. He doesn't have recent work, but has been releasing unreleased beats back in 90's from Slice Of Spice. He has established his style in 90's. As well was Showbiz, I can recognize his beat without a prior information.
