"Try the Bass" is essentially one big keyboard solo by Roland, but man is it a good one. There is a bit more to it than that, though. It's got structural and rhythmic changes that most soloists don't like (there's usually a designated repeating solo section in musical pieces), but Jenkees trucks right on through. Being a new single, there's more material on the way and I'll be waiting to hear it.
