A portion of Nintendo Life's interview with Smooth McGroove:
"Do you think some of these classic video game tunes are more memorable when compared to modern musical works?
I think that limitation breeds creativity. Back in the early video game days, composers had very strict limitations on their compositions due to the hardware. That made every note count, so some truly amazing music came out of that era. I think it works in a similar way to my acapella arrangements. Because I'm limited to my voice, I have to make some interesting decisions when it comes to singing or doing a percussion part. It keeps the process interesting."
