Here's a list of some under the radar stuff I've checked over the last month that I really enjoyed and don't seem to have many ratings. I'll try not to put a lot of 2020 releases in this one because I'll be saving that for my list later in the year.
2014. I actually had a really good writeup for this here but my first list crashed so ehchhhhh. This is pretty varied for the genre, from a 3 min groovy solo bass jam, to the interesting female vocals in the last track Surrender. Everything in between is good, core riffage.
2018. I'll stop it here for now. If enough people like the list I'll go ahead and add 5 more 2020 releases that may have slipped by. I know I added a lot of the albums on this list to here because a good amount just have my ratings on them.
