Don Van Vliet was born to be a cult artist. Van Vliet, better known to most of us as Captain Beefheart, pioneered an unhinged, experimental form of rock ‘n’ roll. He never made much commercial impact, but he inspired generations of artists. One of those artists was young Polly Jean Harvey, who grew up listening to Beefheart because her parents were fans. Apparently, Van Vliet was also inspired by PJ Harvey — or, at least, by PJ Harvey’s cat.
