Awesome Playlist. Exactly my type. Hard Alternative Rock.
Since you like alt rock, maybe you could include a song from this artist in one of your playlists : Zambonia. I think you'll like the song Roots. It fits a lot with your Indie/Alternative Rock playlist.
I know this thread is old, but who knows, maybe someone is surfing for some new tunes to plug their ears into and stumbles across this.
I've really been digging Des Rocs. He has three singles out; HVY MTL DRMR, Used to the Darkness, and the newest, Let Me Live / Let Me Die. I find him creative. He's very rock n' roll. For a more alternative rock sound, Deaf Havana has some new songs out. Holy, **bleep**, and Sinner are all very good alternative rock beats. Violet City by Mansionair is also a good listen.
