Grand Funk Railroad and Jefferson Starship

Jefferson Starship, formed by Paul Kantner and Grace Slick post-Jefferson Airplane, became a '70s-'80s rock powerhouse with hits like "Miracles." Their album Red Octopus topped charts, with Marty Balin's return boosting success. Despite lineup changes, they thrived with a mainstream rock style. After Kantner's 2016 death, David Freiberg continued the legacy, releasing the 2020 EP Mother of the Sun.

Grand Funk Railroad, formed in Flint, MI, by Mark Farner and Don Brewer, is known for its blues-rock sound and energetic live shows. Despite critical pans, they gained a devoted fan base through constant touring. Key albums like "We're an American Band" and hits like "The Loco-Motion" defined their peak years. Collaborations with Todd Rundgren and Frank Zappa marked their style. Although disbanded and reformed multiple times, their legacy continues, highlighted by a benefit album, "Bosnia," and a retrospective box set, "Thirty Years of Funk: 1969-1999."
