Some mashup ideas come from way out of left field, like this combination of Carly Rae Jepsen's inescapable early-2010s pop hit "Call Me Maybe" and the genre-bending jam band Phish's 1993 B-side "Sparkle".
I admit this is far from my best work, but it's been stuck in my head for quite some time, and I wanted to find out how it would sound in reality. Besides, there are plenty of "Call Me Maybe" mashups out there, but none quite like this. (Probably for good reason, I suppose.)
