OK,the Pixies are my all-time favourite band, so I was always going to love this- the concert performances are wonderful and they capture the band’s delighted amazement that a) they can still cut it as performers after nearly ten years apart and b) that a young fanbase has come to love their music despite the band’s rather modest commercial success in their first incarnation- but the insight into the backstage and offstage lives of the four godparents of grunge is what really sets this documentary apart. They are quietly nudged into exploring the tensions that tore the band apart in the first place, and which clearly are still simmering, and their struggles with addiction, relationships and ailing parents are affectingly laid bare. All together now…Cariboooooooouuuu…….
