Finally I can say "I liked them before they were cool"

Some people are saying that the chiptune band Anamanaguchi is going to get big and escape the chiptune scene ghetto. This would, I think, be pretty great. Not only do I like chiptunes in general, but Anamanaguchi is clearly one of the best chip groups out there. As mentioned int he first linked article, chiptunes really make people strip the song down to it's bare essentials, and the most popular soundchips (those that were in the NES and Gameboy) also need very short songs, so the best chiptunes end up being 2 minute explosions of pure melody. As also mentioned, chiptunes are one of the easiest genres of music to get involved with: you can use a free program like FamiTracker to write songs. You don't need expensive instruments, or sample libraries (though those help).

Read about and download their music, and that of other chiptune artists, at 8bitpeoples. Be sure to checkout nullsleep and Random if you head over there too.
