On April 24, Los Angeles, CA’s Grammy Museum will hold a conversation with Jefferson Airplane members Jorma Kaukonen, Grace Slick and Jack Casady.

Kaukonen founded the Airplane in 1965 with Marty Balin and Paul Kantner, with Casady joining soon after that and Slick coming in on vocals in 1966. Kantner and original vocalist Signe Anderson recently passed away on the same day in late January of this year.

Pre-sale tickets to the conversation event, which will take place in the Clive Davis Theater and will be hosted by Grammy Foundation Vice President Scott Goldman, are available to American Express members starting today, with general ticket sales beginning April 14.
