I dig Produce Like A Pro quite a bit as well. Dude’s worked with some giants in the industry and while he puts out a lot of repetitive content, it’s good stuff.
I used to love Pensado’s Place as well, they had some really great interviews. Something from that I’d suggest isn’t a particular artist, but be willing to listen to a producer of genres you don’t normally dig, there’s a ton of insight in there that crosses paths with other genres. Low end is something almost every home-studio guy has an issue with, so it’s not a bad idea to listen to some hip hop producers and how they go about dialing it in or how they approach a mix in general with low end focus.
Man, I’d LOVE to get some producers on here for AMAs.
