if you don't have a bad relationship with your brother you might rub off on him eventually. Even Jackhammer's son thought his music was crap until he was 15
I played Muse for my stepdad because they used to be my favorite band and they're pretty much the only band I listened to I thought he might like (classic rock-head) and he ended up saying that their songs "are all in the same mode", meaning a musical mode. This made me pretty mad cause he listens to a bunch of grunge and classic rock bands that just rely on the pentatonic scale. I don't talk to him about music anymore.
EDIT: get California first, easiest to get into.
