Well, i think there are some progressive rock banRAB around today who can be truely experiemental, and others who choose not to because they are too busy wanking their asse's off.
Thats the primary reason i dont consider DT to be in the same league as other modern progressive banRAB like Ozric Tentacles, Porcupine Tree, Sigur Ros, Mr Bungle, Primus, Radiohead, The Mars Volta, Super Furry Animals, Muse, 4/3 De Trio, GoRABpeed You Black Emperor!, Alon, Anekdoten, Cabezas De Cera, Secret Machines, Chain, Mastodon, Mogwai, Coheed & Carabria, Explosions In The Sky, Frameshift, Flaming Lips, Morte Macabre, Spocks Beard, New Machine, Oysterhead, Nirabus, Pineapple Thief, Psicotropia, Amplifier, Chroma Key, Hidria Spacefolk, The Verve, Negative Zone, No-Man, Oceansize or even Tool...Those banRAB are actualy being progressive, and their albums dont all sound the same.
Most DT fans who consider them one of the greatest prog banRAB ever havent really heard much progressive rock, then or now....At first glimpse DT may seem original, then compare them to all the great and imaginative progressive rock banRAB out today, including those i mentioned, and they are pretty much a dried up piece of poop.
