Geddy Lee has told Premier Guitar in a new interview that he doesn't know what his next musical project is going to be. The RUSH bassist/vocalist, who recently released a book called "Geddy Lee's Big Beautiful Book Of Bass", explained: "I'm afraid I don't really have a plan at this stage. I don't know where I'm headed musically. My attitude is that I've been part of an amazing collaboration with two guys that I have so much respect for and for so many years, and we were very purposeful in our time together. The book has been a very cool way for me to transition out of that scenario, and now I feel like I'm in a position to truly clear the deck and hit the reset button, and see what I have to say musically. I need to give myself time to experiment with that and see what comes out that I feel strong enough to be a worthy thing to do next. I have no idea where that's going to take me.

"When I mess around at home, I'm sort of all over the map," he continued. "But that's also usually how a RUSH album starts. I don't imagine that whatever I do next will be drastically different, but because I have more guitars now, I'm playing more guitar in the studio and getting ideas that way. Stylistically speaking, I never felt like I was missing anything in the context of RUSH, because anything goes in that group. When I jam, I jam all over the place, but whether or not I'm going to follow it any one specific direction in the future, I have no idea. I never had any musical frustrations in RUSH. It was a totally fulfilling experience for me."

To date, Lee has only released one solo album, 2000's "My Favourite Headache". The disc was recorded during a time when RUSH's future was uncertain. The band was in the midst of what would be a five-year break from the road following the tragic deaths of drummer Neil Peart's daughter and wife in 1997 and 1998, respectively.

"Geddy Lee's Big Beautiful Book of Bass" documents the evolution of the bass guitar since the 1950s and shows how those evolutions changed the sound of popular music as we know it. The book includes photos of Lee's massive bass collection, as well as interviews with fellow bass players like John Paul Jones of LED ZEPPELIN, Bill Wyman of THE ROLLING STONES and U2's Adam Clayton.

RUSH has been completely inactive since completing its "R40 Live" tour four years ago.
