The Book Of Knots is a veteran American underground band that takes its name from Clifford Ashley's encyclopedia of knots. Their music is wild, tangled, and follows only its own crazy logic, but with a grandiose concept and collaboration with various artists such as Tom Waits, Zeena Parkins, and Mike Watt. Traineater is their album released in 2007, featuring 14 tracks with a mix of instruments and vocals.
