Good Vibrations is a good film from 2012. It is set in 1978 in Belfast and is about record shop owner Terri Hooley who owned the record shop of that name. He helped local punk bands to get gets out by starting a record label of the same name. He also discovered punk chart busters The Undertones as well. It is well worth a watch.
