Hidden Orchestra is an electronic jazz collective based in Edinburgh. Their debut album Night Walks was released in September 2010. The group was previously known as the Joe Acheson quartet.
Besides jazz they are using elements of pop, reggae, hip-hop and psychedelic music. Guest musicians, improvising, natural sounds and contrasts combined with electronic effects are supposed to make the music emotional and energetic. The album succeeded all over Europe. It got the "Album of the Month" at BBC Radio 1 and was listed at the iDJ´s top albums of 2010. Hidden Orchestra was added by Radio Scotland at the A-Z greatest Scottish jazz artists of all time. In November 2010 they played in the UK and in March and April 2011 a Europe tour followed. They played headline gigs and supported a couple of other artists in 12 countries. In January 2011 a vinyl deluxe version called "Night Walks on Vinyl" was published on the German label Denovali. A new album entitled Archipelago was released on October 1, 2012.
