by Richie UnterbergerBy the time of Bark, personnel changes had gutted much of the original version of Jefferson Airplane, especially with the departure of Marty Balin. Paul Kantner and Grace Slick remained, but their compositions were growing increasingly ill-focused, and Jorma Kaukonen and new drummer Joey Covington were ill-equipped to pick up the songwriting slack. The result was an album that bore hallmarks of the classic Airplane sound, but lacked any classic Airplane songs. That said, the record isn't as bad as many reviewers have made it out to be. It's just mediocre, with little that sticks in the memory, despite occasional nice moments in cuts like Covington's "Pretty as You Feel" and Kaukonen's delicate "Third Week in the Chelsea."
