Viggo's head slowly turns towards the direction of the criticism, finding a giant red-haired woman as the source. Clutching the neck of his guitar, Viggo strides over to Margaret with an aggressive snarl on his lips. "Hey!" he shouts curtly as he approaches, stopping a few feet away from her, his guitar now held slightly to the side. Viggo's face is fixed with an annoyance, as though he's used to dealing with people unfond of his style of music. 

"You have a problem with my choice of song, ma'am?" he asks with poison to his tone, his fingers independently continue to silently pluck and tap away at the strings and frets in practice. Viggo's eyes quickly flash to the ogre next to him before glancing back at Margaret, making sure that he's not about to be stomped by the giant beast of a man.
