Stephen Stills has long admitted that he's his own toughest critic. While listening back to the tracks selected for his new four-CD, career-spanning, 82-track box set, Carry On, coming on March 26th, he was just as critical as ever, telling Musicradar.com, "When I heard my guitar playing on these songs, I thought, 'OK, he's still learning, He's playing within his limitations. Maybe he'll get good by the time he's 50.'"

Stills talked about how Graham Nash and longtime Crosby, Stills, & Nash collaborator Joel Bernstein handled the unenviable task of compiling the set: "I'm just not the kind of guy who sits around and stares at his own navel. They were planning on making it three CD's, but I said it had to be four. If we were going to do this, we were going to do it one time and have everything on there."

He went on to add that it was quite an accomplishment to distill his career into one package, admitting, "I'm listed as a producer, but Graham and Joel did the lion's share of the work. Going through old boxes of tapes, trying to read credits and titles when the labels have been replaced -- it's a big job. I'm glad they did it because it would have taken me 10 years!"

While the box set was in production, Stephen Stills told us that looking back now, he's simply amazed at some of the stuff which ended up on the cutting room floor: "There is a host of things that was recorded around the time of the second Stephen Stills record. My God, there's just a couple of things that just thrilled me. But there's outtakes and alternate takes, and songs that didn't make the cut that are still sittin' there in the vault. And except for one particular brand of tape -- everything just plays beautifully."
