couldn't get your vid to load..........I'm recommending,"the Devin Townsend Band, Syynchestra" to everyone right now. Heavy, maybe a touch, riffing, yes, melodic and beautiful IMHO, hell, I'm totally enamored with Devin right now, these days. He's got a bunch of projects, he's a geetar player, and, he produces for a bunch of folks.
The guy who mentioned Clutch is on it. Clutch is the shit. Check out the self titled one if you're not familiar with them. Good stuff. It's worth it for the lyrics alone.
My left-field pick would be Autolux......opening for NIN. Spacey, poppy, alt tunings with a chick on the skins, she sings (like an angel) too.
Before Autolux, there was a band called, "Failure". "Fantastic Planet", is a great record. Good guitar stuff. I'm guessing you like guitar stuff, so, that's influencing my recommendations.
I'm thinking you're looking for stuff all over the map. I can help if it's a little heavy. Hippy, jam stuff, I dunno.
Heavy sludgy stoner rock. Old band called, "Beaver". Look for, " The Difference Engine" Try a little band that went on to be a bunch of bands, "Kyuss". "Queens of the Stoneage", and "Hermano" are the notable spinoffs IMHO. "Goatsnake" and "High on Fire", are also two great ones in this genre.
Right now, I like heavy fucking metal and electronica, so I don't know if I'm much help here.
Fave metal thing="Arch Enemy", fave elec thing = "Boards of Canada".
Iffin' you're at all interested in electronic music, I can point you in the right direction.
Cheers!
