Back in the day you used to get amazing musicians coming together to create magical duets. In fact, in the 80's, if your soundtrack didn't have a powerhouse duet, you might as well pack up and go home. Somewhere in the 90's this trend kind of died away, to the point that you don't really hear them at all anymore. I was just talking about this recently with my wife when it hit me...synthwave has totally brought back the duet, just not in their original form. How's that, you ask? I'll give you a perfect example.
Let's take "Desire" by Neon Arcadia and Megan McDuffee. On one hand you have an amazingly talented group of musicians in Neon Arcadia who are fully capable of telling a story with music alone. On the other hand you have pitch perfect vocals of Megan McDuffee soaring over this created audio landscape. The end result finds two personalities...two musical styles blending together to compliment each other on every level. There's a magic in this that doesn't exist in a normal band dynamic, and there's plenty of magic to be found in "Desire."
To prove my point, here's the definition of a duet:
A duet is a musical composition for two performers in which the performers have equal importance to the piece
