Riverboat Sky is a collection of accessible songs written and road-tested by guitarist Carl Verheyen, and his band of virtuoso musicians. Verheyen reflects on how he "learned a valuable lesson, from all those years making records and touring with Supertramp. We always lamented that the record was a demo for the tour, because the songs developed so much more on the road. This time I was fortunate to play the music for a year and a half before committing it to CD and vinyl, so the songs feel much more fully realized. It was a luxury recording music we all knew so well."

This is reflected in the musicianship heard on the album, which includes a masterful duet between Carl and Sophia James – of American Idol fame – on Riverboat Sky’s title track. The supporting musicians consist of Verheyen’s regular touring band – Dave Marotta (bass), John Mader (drums) and Troy Dexter (keyboards); who are supplemented by Jim Cox, Alex Acuna and Chad Wackerman.
