What constitutes a ‘solo’ album? Some artists fill the studio with a whole plethora of hired help but I don’t go that route. I work alone methodically to create a recording. Guest vocalists I feel don’t distract from the core of what I want to do, in fact they make it more worthwhile for me. I don’t think I compromised on the talent on ‘Slope’, which is important. For me it’s an album of people doing what they do best, and yet the list of contributors is fairly minimal. I’ve worked on many solo artist’s recordings and they are often anything but.
