Bruce Haack, born on May 4, 1931, was one of the most musically and lyrically inventive children's songwriters of the '60s and '70s. Despite -- or perhaps because of -- his intended audience, his music was unusually expressive, combining homemade analog synths; classical, country, pop, and rock elements; and surreal, idealistic lyrics. Haack's innovations and desire to teach still sound fresh, making his music a favorite with fans of analog synths and esoteric recordings. Followers like Luke Vibert and Add N to X championed his unique musical vision, which embraced concepts like "powerlove" and turned household appliances into synthesizers and modulators.
