Dont call it hard rock. Dont call it acid. Dont even call it neo-fusion. Some of them say they play band music. Others sneer saying band music sounds infra-dig, and they play folk rock. They also insist the Rolling Stones are a folk-rock act. Never mind. A few others say they play neither rock, nor grunge, nor folk. Just something indefinably "different". What it is, straight up, is Bangla rock: spirited callow vocals belting out homespun lyrics about life, love, lollipop and loneliness set to a smorgasbord of largely borrowed - or inspired - sounds. Its also the current rage in Bengal.
