to answer your question chanel,
you can find them mainly around big cities such as los angeles or new york. just go to the indie clubs over there and youll see 200 scenesters walking and dancing around. worst scene "hell" ive been to has been at club moscow in los angeles. they play ok music but the crowd.... :S i guess misshapes and cobrasnake are sort of scene, although the latter people dress really in a horrible way! mostly just some normal guys in large buttonup shirts and loose jeans with tennis shoes. or hippie boho girls. yuck!
indie music/scene music is emo, hardcore, indie, old punk, new wave.. mainly bands like the killers, the bravery, the cure etc. which are not that bad i guess...hardcore kids and music are hard to stand imo.
