I like Dream theater yes. I've listened to them since their 2nd album and saw them live on the "Awake" tour. I admit, I don't listen to them as much as I used to but still consider myself a fan.
New stuff that don't sound old....hmmm, I like the Knife for some reason but I can't recommend them as they sound too retarded, José Gonzales (well, sounds like Nick Drake), some Bo Kaspers Orkester (ripped off Miles and every other jazz band/musicina but...) records. There's not an awful lot that interests me to be honest. Yes, I still adore PT and Katatonia and some Madder mortem, some Meshuggah etc but really, I'm stuck in the old days. Right now there's a lot of Miles Davis, "In a silent way" has been playing around 5 times every day for the last months and same with "E.S.P"....
