Robert Steven "Adrian" Belew (born December 23, 1949) is an American musician, singer, songwriter, and record producer. A multi-instrumentalist primarily known as a guitarist and singer, he is noted for his unusual approach to the instrument, his playing cited as fluid, expressive, and often resembling "animal noises or mechanical rumblings".
Widely recognized as an "incredibly versatile [guitar] player", Belew is perhaps best known for his tenure as guitarist and frontman in the progressive rock group King Crimson between 1981 and 2009.
