This week, without any official announcement, the Rock Hall revised the official biographies on their website for Rush, Heart and Public Enemy to confirm which members were included in the Hall of Fame induction.

For Rush, obviously Geddy Lee, Alex Lifeson and Neil Peart are being honored. John Rutsey, who was the drummer on Rush’s debut album, is not being inducted.

Only the original 70’s era members of Heart are getting in, despite the band’s continued success in the ensuing decades with other members. The inductees are Ann Wilson, Nancy Wilson, Roger Fisher, Steve Fossen, Howard Leese and Michael DeRosier.

Only four members of first ballot Hall of Famers Public Enemy are being inducted -- Chuck D, Flavor Flav, Professor Griff and Terminator X. The Bomb Squad, the influential production team behind PE’s sound, are not included, nor is current and longtime member, DJ Lord.

Deciding which members of Hall of Fame groups to induct is often a sensitive and complicated issue, especially for bands that have been around for decades with multiple lineup changes. The Rock Hall doesn’t publish any criteria for how they determine which members to induct, likely because it gets handled on a case by case basis (for example, see 2012 for all sorts of strange contradictions).
