I think this is going to be a really tough one for you ! ! !
I was listening to More More More which is the latest album by Stereopony and the opening track is called Introduction. It is a short track where Ami (the singer and guitarist) just says a few words about the band in English.
So I started to think about it and I have only 3 tracks where the bans introduce themselves. One other Japanese track and one English.
So I think this will be a tough challenge for you.
What are your favourite Meet The Band tracks ? ? ?
Here is Stereopony with Introduction:
