Adrian Utley (Portishead) brings together an orchestra of electric guitar players to interpret Terry Riley's 'In C'. Written in 1964,'In C' is one of the most influential pieces of music from the 20th Century, it established minimalism as a music genre. In C's simple musical rules - 53 musical phrases in C and no duration - allow for infinite variations. Utley's impressive Guitar Orchestra is augmented by organs and a clarinet making for a mesmeric sound experience. The Guitar Orchestra consists of 24 musicians from Bristol: 19 guitarists including John Parish (PJ Harvey), Thought Forms, and Jim Barr (Portishead live band); 4 organs and a bass clarinet. The effect is an organic musical experience very much created in front of the audience both fragile and thunderingly uplifting. The album was recorded live at St Georges Hall, Bristol, one of Britain's leading concert halls which is known for its astounding acoustic and unique atmosphere.
