The Howlin' Wolf Album is exactly what you're looking for. It is not the best thing Howlin' Wolf ever did, but it's pretty awesome and I don't really understand why I've never seen anyone talking about it. I think I am actually the only person who enjoys this album. It's definitely not his best album and he never did anything else like it (apparently he hated it) but it's not at all terrible or anything.
Howlin' Wolf - SpoonfulListen to that song. That's what the whole album is like. It's psychedelic but entirely blues unlike the stuff you posted, which is blues rock. It's pretty cool and I think you'd like it, so check it out. There's also
Electric Mud by Muddy Waters which is really similar, but I don't think it's as good (I haven't listened to it as much yet though!)
Pretty sure critics hate both of these albums.
