A warm, satisfying thrill coursed through Oliver's veins. He was wandering through a music festival, and there it was - his abstract 'Soundwave Symphony' design, tattooed on the back of a guitarist. He made his way to the front of the stage, unable to prevent the smile that was now plastered across his face.

He watched the band set up, his heart thrumming with anticipation. As they began to play, Oliver started to dance, lost in the music. It was just as he had imagined.

After the song, Oliver approached the guitarist, his expression one of pure glee. "You, sir," he began, his voice barely above a whisper, "have exquisite taste." He pointed at the tattoo, his eyes dancing.

The guitarist grinned, clearly amused. “Thanks! I love that piece.”
