The Lazy Man's Music Drug

As he lays down on the back of his insect creature he plays his instrument that makes him feel drowsy and sleepy, while his insect mount is affected in exactly the opposite way and is very awake and energetic.

This concept is a bit based on the music drug called i dosing, where music should give you the same effects as any kind of other drug. Though i haven't used it myself it did inspire me to make this.

You could also make an alternate story of this, that a guy's just tripping and sees that he has a giant trumpet in his hand instead of a sig and sees this weird creature underneath his bed.

Hope you like this concept anyway
