How a Dylan impersonator might sing

NASALLY

Think of the way someone with a cold or allergies might sound when speaking, especially if they're trying to mimic a famous folk singer's distinctive voice.

This clue plays on Bob Dylan’s distinctive singing voice, which some describe as nasal. The word "impersonator" hints at mimicking that style, so the answer is a punny take on how someone might sing like him—"nasally." It’s a straightforward definition with a touch of humor, relying on the common observation about Dylan’s vocal tone.
