[3] The Capitol was utilized as a concert space throughout the 1970s, 1980s and 1990s, and featured performances by such acts as Pink Floyd, Johnny Winter, Rick Derringer, Talking Heads, the Grateful Dead, Rubén Blades, Janis Joplin, Parliament-Funkadelic and Traffic.

Both David Bowie and the Rolling Stones performed at the Capitol in 1997, as part of episodes of the MTV television program Live From The 10 Spot.

[6] The theatre later became a catering and special-events facility, run by owner Marvin Ravikoff and managed under the leadership of Jim Lopolito from October 2001 to December 2011.

The lower level seats were removed to create a flat space for tables and a dance floor for weddings, Bar Mitzvot and other events.

Part of the renovations included acquiring the adjacent Capitol Jewelers store and converting it into a bar, which is open to the public most nights when the theatre does not have an event.

In 2013 the venue hosted Dawes, Blondie, Pat Benatar, Billy Idol, the Rascals, and Chicago, and scheduled Neil Young, Willie Nelson, Chris Isaak, Yes, Foreigner, Patti Smith, Courtney Love, Bonnie Raitt, Jonny Lang, Cyndi Lauper, Herbie Hancock and many other top performers.

On December 11, 2015, Bo Burnham's stand-up special Make Happy was filmed at the Capitol Theatre and released on Netflix the following year.
