-- Otaku Vengeance (http://www.OtakuVengeance.com) -- Home of my mentor and first supporter, Eric. One site containing 3 amazing talents, Eric, Lord Rae, and Viggigolo. MANY high quality AMVs.
-- More Than Toast (http://www.MoreThanToast.com) -- Another site containing 3 talented editors; Akimbo, Kwasek, and Grungetta. There are many award-winning AMVs here. The site also contains more humor than your average AMV site, and the sites worth a look just for that.
-- Cryptonight Studios (http://www.Cryptonight.net) -- Home of Shiniryu, Ambika, Lifehost, and Akashio. Whew. Shiniryu has a style similar to Aaron's, yet distinctly different. If you enjoy Aaron's videos, you'll enjoy Shiniryu's. To be quite honest, I haven't seen any of Ambika's work. She was just recently added to the site, so I haven't had a chance to check any of it out. I'll update this when I finally do get around to doing so =].
-- Blind Guardian (http://www.Blind-Guardian.com) -- Without a doubt, one of THE most talented bands EVER. I've yet to hear a sub-par song from them, and I doubt I ever will. The wonderful blend of power metal and harmonic voices is just awesome to listen to. The lyrics, also, are of notable mention, as they sing about fantasy-related subjects.
-- Insane Clown Posse (http://www.InsaneClownPosse.com) -- This is one interesting rstyle of rap. Their lyrics range from morbid humor to just plain-out perverted humor. The music itself ranges from upbeat to darker, serious tones. While I typically despise rap, I cant help but love ICP.
-- Big Dumb Face (http://www.BigDumbFace.com) -- This is THE definition of strange and unique music. This side-project of Limp Bizkit guitarist, Wes Borland, surely defines strange and unusual. The band has a wonderful sense of humor, and some real guts starting a project this out-of-the-ordinary, and I'm really glad they did.
-- Beastie Boys (http://www.BeastieBoys.com) -- I'm sure by now everyone's heard of them, but I still have to mention them here. They have been around since the 80's and on every album their music style seems to change. Starting off as a more rock-based group of fun-loving teens, they have matured to a more hip-hop group of adults who really seem to have a passion for their music.
-- Incendiary Tetsuo's Akira Site (http://IncendiaryTetsuo.cjb.net) -- My ol' IRC buddy who was one of my first friends when I started going on the 'net. He's the one who saved my ass (and the site) by providing hosting for the videos. Without him, this site would have probably been extinct by now.
