Black Angels (Edition Peters, New York, no. 66304, copyright 1971), subtitled "Thirteen Images from the Dark Land", is a work for "electric string quartet" by the American avant-garde composer George Crumb. It was composed over the course of a year and is dated "Friday the Thirteenth, March 1970 (in tempore belli)" as written on the score. Crumb is very interested in numerology and numerically structured the piece around 13 and 7. The piece is notable for its unconventional instrumentation, which calls for electric string instruments, crystal glasses, and two suspended tam-tam gongs.


Black Angels is primarily written for (in Crumb's words) "electric string quartet." Though generally played by amplified acoustic instruments, the work is occasionally performed on specially constructed electronic string instruments. The music uses the extremes of the instruments' registers as well as extended techniques such as bowing on the fingerboard above the fingers and tapping the strings with thimbles. At certain points in the music, the players are even required to make sounds with their mouths and to speak.

Each of the string players is also assigned a set of instruments to play throughout the piece. Some of the equipment requires specific preparation, such as the crystal glasses, which are tuned with different amounts of water.

Stage positioning[edit]

Crumb's score includes a diagram that places the four musicians in a box-like formation. Electric Violin II and Electric Cello are located near upstage right and upstage left, respectively, with their tam-tams between them. Electric Violin I and Electric Viola are near downstage right and downstage left, respectively, but are slightly farther apart than the other two musicians in order to allow full sight of the quartet. Violin I, Violin II and Viola have a set of crystal glasses downstage of them, while Violin I and Cello have maracas upstage of them. Each of the four musicians has a speaker next to him or her.

Cultural influences[edit]

The Kronos Quartet, which specializes in new music, was originally formed when violinist David Harrington heard "Black Angels" over the radio.[1] He thought Crumb's piece was "something wild, something scary" and "absolutely the right music to play."[2] It was the first composition Kronos performed.[2] The Kronos Quartet recorded the work on their album Black Angels.

"Threnody I: Night of the Electric Insects" is featured on the soundtrack of The Exorcist.[3]

"III. Return - God-music" is heard in the television series Cosmos: A Personal Voyage on the third episode of the series titled "The Harmony of the Worlds".[4]

The record is mentioned by David Bowie among his 25 favorite records[5]
