Guitarist Matt Roberts of American rock band 3 Doors Down was recently interviewed for Gibson.com. At one point in the interview he's asked the question Who has really impressed you in the business? and here was his response:
... Alex Lifeson has become a good friend of mine. He's been really inspirational to me. He's a great guy. It was awesome to be able to work with Alex. We did some recording with Alex. I never thought I'd be playing guitar with Alex Lifeson. Great guy. Great musician. ...
Alex produced 3 songs for 3 Doors Down back in 2000. You can watch the interview below or at this link at about the 1:30 mark. Thanks to RushFanForever for the heads up.
