On 'Hidden Knowledge' the Lamp's sole member Craig Williamson ramps up the trippy space factor. You get four tracks that cover early Pink Floyd-like excursions, '70s Kosmische Musik, astral folk and meditative eastern influenced jamming. And of course all the tracks are performed in that distinctive Lamp Of The Universe style. So prepare yourself for another journey to the center of your mind and deep into space! Includes one bonus track.
