Roger Keith "Syd" Barrett was an English singer, songwriter, and musician who co-founded the rock band Pink Floyd in 1965. Barrett was their original frontman and primary songwriter, becoming known for his whimsical psychedelia, English-accented singing, literary influences, and stream-of-consciousness writing style. As a guitarist, he was influential for his free-form playing and for employing dissonance, distortion, echo, feedback, and other studio effects.
