THE YOUTH want to be suited and booted and spit out contagious rock'n'roll. They want to play songs that anyone can under-stand, a beat that everyone can fall in love with and a groove that everyone can feel. The Youth want to bring sixties sounds back into teenage bedrooms-where it belongs. The Youth formed a couple of years ago in Copenhagen when four friends decided to combine their shared passion for blues, garage-rock, rhythm'n'blues and beat music. They have already made a name for them-se.
