A "type of dance music, played on electronic instruments and with a slow beat", according to Longman Dictionary, trip-hop (also known in the past as the "Bristol sound") is, in fact, a musical movement that started in Bristol, UK. The tag isn't limited to Bristol-based bands though; bands as far as Canada (eg. Perfume Tree) or Costa Rica (eg. Úztari) have been considered 'trip-hop'. Many 'trip-hop' bands like Massive Attack, Portishead or Tricky have denied the term though, claiming it to be "an invention of media journalists". (It was in fact coined by Luke Vibert aka Wagon Christ).
