You have 3 different genres up there. Grunge Rock, Alternative Rock and Psychedelic Rock. You could probably group them all under Alternative Rock and start there. Check out Stone Temple Pilots, Pearl Jam, Radiohead, Muse, White Stripes... I could go on for an hour because you left a very broad window.
Sorry no help with the second set, no knowledge there. You don't sound stupid by asking for help to broaden your music collection... Stupid would be listening to one tiny genre and ignoring the rest of the music world!
shit haha...sorry.. to me usually new genres sound the same/I can't really differentiate...): All I know is that they sound good haha
Thanks though, really helped!
