Bo Jackson/Super Tecmo Bo are Tea in China are my favorites on that list but I'll give a quick cliff notes:
My 1st Chemistry Set: The 1st Alc and Boldy album. Hardest batch of production Al dropped in the 2010's, and Boldy sounds raw, but the talent is there. Rapping wise he's better now, but this is an album full of bangers. Boldy and Al wouldn't reunite for another 6-7 years.
The Price of Tea in China: 2020 album from Boldy and Al. Most would probably say this is their best album together. If they're MadGibbs, then this is their Pinata. Very dark and gritty and cohesive.
Bo Jackson: 2021 album. Boldy and Alc's follow up to Price of Tea. If they're MadGibbs, this is their Bandana. It's more colorful sounding and vibrant than Price of Tea. Not quite as dark. But Boldy is even better as an emcee and it's my favorite project they've done. Boldy arguably out raps all the guests.
Super Tecmo Bo: Short album that dropped December 2021 by Boldy and Alc as a companion piece to Bo Jackson. Only 9 songs, and only one feature. Very unique, and it might be the first project I'd recommend for people that want to appreciate Boldy as a rapper. The vinyl drops this Friday BTW at noon EST.
Real Bad Boldy: 1st Collab album between Boldy and Real Bad Man, from 2020.
Killing Nothing: Follow up to Real Bad Boldy and a good deal better IMO. Boldy is just a much better rapper in 2021 and 2022 than he's ever been.
EDIT: vinyl link for this Friday. Open pre-order:
Super Tecmo Bo (LP - Black Vinyl)
