Your twin brother, Jackson, has been a bit punk rock. He was a former choir kid who, despite not missing the excruciatingly slow and boring songs the old teacher had taught in that class, found himself restless without a place to perform.
Your entire family was less than surprised when he announced he'd started a band with some school friends. Today, he brought his still unnamed band back to their house for what Jackson had declared was a 'Jam Sesh'.
This was not a Jam Sesh, though. This was actual torture. You'd expect them to have some semblance of unity, maybe one common song they all knew how to play but you were sorely mistaken. Instead you got an amalgamation of 5 different keys, tempos and tones that combined to create a symphony seemingly designed to make your ears bleed.
