CC might be my vinyl purchase that I'd have the hardest time parting with. It's in my top 3 favorite releases of the 2010's. I have so many great life memories to that album, and it changed my entire perspective on hip-hop too. It got me out of only listening to either goon music or blue collar rap. Spitta really changed my perception on what made a good emcee and opened my ears up to a new style of rapping. And Alchemist's production got me out of the only enjoying either 'tunnel banger' street joints or soul sample beats. It got me interested in hazier and more psychedelic trippy production. Finally, it also exposed me to a lot of dope European and Asian music by way of the samples that were used on there.
Edit: Also CC is a trip because there's very little info out there on how it was made.
