Jefferson Starship will perform at 8 p.m. Friday, May 19, at The Showroom at Isleta Resort & Casino. The band is one of the most successful arena rock groups of the 1970s and '80s.

Iconic Bay Area rock band Jefferson Starship is 50 this year. We caught up with founding member David Freiberg and lead vocalist Cathy Richardson to talk about the band's roots and its evolution.
