Some bands / artists I've been following for a long time are (among others) Massive Attack, Pink Floyd, Pet Shop Boys, Archive, A-Ha, Yes, Porcupine Tree, John Mellencamp, Jean-Michel Jarre, Metallica, Peter Gabriel and Perturbator. So my music will kind of sound like those (without ever reaching the greatness of those artists, of course). :-)
