Jefferson Airplane continued issuing hit albums through the end of the 1960’s but was beginning to run out of steam, so its members began spreading out and working on solo albums and side projects. When Grace Slick was recovering from throat surgery, Hot Tuna was founded and had a oft-changing line-up of various members of the Airplane and others. Electric violinist Papa John Creach joined Jefferson Airplane and Hot Tuna at the same time.
