Ziggy Ferias is a singer, performer, “orphan vampire child.” (His last name sometimes spelled as Farias).
Ziggy is a significant figure in the story, both musically and as Daron’s love interest. Ziggy is charismatic, talented and difficult. We see him through Daron’s eyes except for a brief POV change where Ziggy takes over as narrator.
A talented singer would be ideal but (as with Daron), the charisma and ability to work with a range of complex motivations is as desirable as musical talent.
