Henry Cow were an English experimental rock group, founded at the University of Cambridge in 1968 by multi-instrumentalists Fred Frith and Tim Hodgkinson. Henry Cow's personnel fluctuated over their decade together, but drummer Chris Cutler, bassist John Greaves, and bassoonist/oboist Lindsay Cooper were important long-term members alongside Frith and Hodgkinson.
