I had no idea what would happen when I said yes to a friend's invite to check out a show at the Music Museum last week.

The performers were virtually unknown to me: Rachel Gabreza, Kier King, and Lily — though the last one sounded familiar, as in Callalily.

I heard shrieking voices upon reaching the first door to the Museum's concert hall, which had a full-house audience.

Onstage was Gabreza, who was belting out a difficult number. Her high-pitched vocals reminded of a young Charice Pempengco, with hints of Aegis.

As I belatedly found out, Gabreza was a quarterfinalist at Tawag ng Tanghalan season 1 in 2016. Though she didn't advance to the finals, destiny has been kind, since Gabreza has been active as a performing artist — with a horde of screaming fans.

King, meanwhile, had joined Popstar Kids, Bet ng Bayan, and other singing competitions — including Idol Philippines. If Gabreza is a birit queen, King is her male counterpart — a young artist who can hit the high notes of the ballads he sang at the show.
