I'm 38, and lived in Japan from '97-'02. While there one day in the subway I met an American guy with feathered hair, comb in back pocket, high tops, and white shirt w/broad vertical stripe pattern. Just like I might have dressed in high school circa '87. And sure enough, he came to Japan in the late '80s. The point? You have to always find new music, or you're
that guy.
If you are in front of a computer all day like I am,
www.slacker.com is a great site for band discovery. In addition to genre stations, like idie, hip hop, etc, you can input an artist you like. They will rotate through a bunch of similar artists and you will generally find a few new ones...
Alternatively, if you like indie, check out
www.kexp.org a public radio station in Seattle. I've found about 50 new bands I absolutely love listening there...
Another perennial favorite of mine is
http://www.avclub.com/content/home. Every year at new year they have all of their record reviewers do a best of the year list. I generally find a reviewer who has at least one person I know in their list and triangulate with other reviewers to whittle it down to a manageable 2-5 artists to check out.
Just a few suggestions. I don't want any of my new friends to be
that guy...
As for me, I listened to a bunch of Death Cab while tiling the bathroom, and now am going through some old Burt Bachrach records. New and new to me...
