British electronic wizards Underworld released their seminal record Dubnobasswithmyheadman in 1994, and in celebration of the album’s 20th anniversary, Rick Smith and Karl Hyde participated in a documentary about its creation. The two-part documentary includes performance footage and testimonial interviews, giving some insight into the process of creating Dubnobasswithmyheadman as well as an account of how Underworld translated the album to a live setting. Smith commented that Underworld prepared every bit of technology in advance to make sure it performed to its fullest capability, and that the group did not rehearse before taking the record to the stage. “It was all about the pressure of the moment, and the failing, and the recovery,” he said.
