Patti Smith Group was a rock band formed by singer Patti Smith in 1974. By 1974 Patti Smith was performing rock music herself, initially with guitarist and rock archivist Lenny Kaye, and later with a full band comprising Kaye, Ivan Kral on bass, Jay Dee Daugherty on drums and Richard Sohl, on piano. Ivan Kral was a refugee from Czechoslovakia, fleeing in 1968 after the fall of Alexander Dubček. Financed by Robert Mapplethorpe, the band recorded a first single, "Hey Joe" / "Piss Factory", in 1974.
