The Miles Davis is an archival live release from a 1969 concert. You might say it's cheating to include it in a 2020 list considering it's a 50+ year old recording, but really, it's so good it deserves a mention of its own. 😄
And yeah, most of these acts are fairly obscure or underground, certainly scraped the bottom of the barrel to get to some of them, but I do think these records are all very good and ones I would recommend. On the link there's a series of genres for each of the records, in case any of them call out to you and you'd be intrigued about checking them out! Also certainly not all artists on the list are unknowns - there's the likes of Run the Jewels, Kylie Minogue, Lianne La Havas, Jessie Ware, Kali Uchis, Charli XCX and others who've all had pretty huge hits this year and in the past!
