I’m kinda in a transient phase where I don’t know what music I’m really into at the moment. Still love Massive Attack, Orbital, and Underworld though.
Eh, not sure who my favorite band is. Does it have to be a band? 'Cause I like classical music more than anything else, especially Beethoven and Johann Jr. Strauss.
Weezer, The Cranberries, Incubus. Countless other rock bands. And alternative. And some metal. And some other shit.
The Cure. or Wolf Colonel/Jason Anderson.
Pearl Jam.
Other favourites of mine include Collective Soul, The Cult, Rush, Soundgarden, and Alice In Chains.
