The first performance of The Fantômas Melvins Big Band was back on New Year's Eve 1999, causing mayhem at Slim's in San Fransisco. The two bands, performing as one supergroup, drew from each other's influences to create a rock explosion. Seven years later and the two groups reunite for an exclusive live performance at the Kentish Town Forum in London. If and when they play next no one knows, but be prepared for it at all times; there is no guarantee of an advance warning to this once in a lifetime supershow.
