The Samuel Jackson Five is another amazing band whose works can be abused as #productivity music (even though they're massively more proggy than #TheAmericanDollar, #BSBD, #Emancipator).
I was very lucky to have attended their concert in #Riga, #Latvia in 2013 with my good friend. It's sad they've disbanded.
Here's their 2005 work — https://www.youtube.com/watch?v=uaBNVGBkNHc, and here's how one can purchase .flac / .mp3 of my favourite album by them — https://denovali.com/digitalstore/index.php?main_page=product_info&products_id=1599&gid=2
I suggest literally everyone to purchase it from #denovali to support independent, ethical art.
(Pinging @jkreeftmeijer with more productivity music).
