From 1965 through 1971, Marty Balin shared lead vocals with Grace Slick in the psychedelic rock band, Jefferson Airplane. In 1975 he joined the offshoot of Jefferson Airplane when he became a member of Jefferson Starship. But before becoming a member of either band, he had two solo singles for the Challenge record label. Both “Nobody But You” and “I Specialize in Love” were released in 1962 and each is worth up to $200.00 today.
