In college, my roomate and I were always trying to go further with the music we listened to. More experimental. Different. Who is doing new things with the old drum, bass, guitar arrangement? This led my roomate into noisy things. Breakdowns of breakdowns. The end of pop/rock music. And it's a big world. People have been exploring that place for some time now.
For me, this had a different effect. Instead of curiosity I just got bored. Rock music can only go so far until it turns into noise. Maybe there are different shades, but they don't excite me. Because what's obvious is that these people are just playing with different ways of looking at a dead end. So I moved on. First I found classical music, because that was an avenue that was always appealing to me, and it is a massive world that took longer to get massive than the other. Then the music of Astor Piazzolla, the various tango quartets, over to Salsa, the music of the Caribbean and so forth. The world is a pleasing tray of delights--some delicate, some raunchy, all worth having--too much for any one person, but I'll keep filling my plate.
