Pronk (sometimes referred to simply as Progressive punk or Prog punk) is an music genre that originated in the late 1970s, following the mainstream success of punk rock. Pronk is generally faster, thicker, complex, and heavier than earlier punk. Pronk has spawned the Soft-punk movement, Pronk was heavily involved with the rise of the independent record labels in the 1980s, and with the DIY ethics in underground music scenes. It has influenced a number of music genres which have also experienced mainstream success, such as alternative rock, grunge, thrash metal, emo and post-pronk.
