‘Psychedelic’ is a buzzword being used a lot these days, especially to sell evermore obscure treasures dug up from the world’s once lost, now rediscovered, international musical archives. In some instances calling the music ‘psych’ is a bit of a stretch – just because it’s weird or dressed up in imported trappings from the same era does not make it necessarily so – and at other times it seems to be merely cashing in on a trend. Happily this is not generally the case when applied to cumbia, because this venerable genre of Colombian music with an international reach truly did go through a psychedelic period. Especially in Peru, where it is also experiencing a genuine resurgence of interest among contemporary musicians and audiences alike, from South America to the United States, Europe and beyond.
