Works, later reissued as Works Volume 1, is the fifth studio album by the English progressive rock band Emerson, Lake & Palmer, released as a double album in March 1977 on Atlantic Records. Following their successful 1974 world tour, the group took a break from recording and touring. They relocated to Montreux, Switzerland and Paris, France to record a new album. Each member was allocated one side of a vinyl record to write and arrange their own tracks which were performed by the group. The fourth side features songs written by the entire group. Emerson wrote his Piano Concerto No. 1, Lake wrote several songs with Peter Sinfield, and Palmer picked tracks of varied styles.
