Cork singer-songwriter Stephanie Rainey's future on America's Got Talent remains uncertain as she awaits tonight's results show to find out if she will advance to the semi-final stage.

She performed for the judges on Tuesday's live quarter-final show on NBC Television in the US.

Despite delivering an impressive performance, she did not receive the golden buzzer that would have secured her a spot in the finals.

The contestants included Stephanie Rainey, Brent Street, Erica Rhodes, Illya & Anastasia Strakhov, Jonathan Burns, L6, Oscar Stembridge, Pranysqa Mishra, Sebastián and Sonia, Solange Kardinaly, and Tonikaku.

This time, Stephanie performed another of her own compositions, a song called 'and,' which expressed her feelings and her mother's struggle with cancer.

This heartfelt performance moved everyone emotionally.

Judge Sophia Vergara said Stephanie's presence on stage felt 'so personal.

' Howie mentioned that the contestant's songs were 'powerful,' but there was something missing on stage.

Simon Cowell said that the production lacked minor details, but the overall singing was impressive enough to earn her votes.

It was Simon Cowell who pressed the golden buzzer during the show to send an act straight into the semi-finals.

The British judge and producer pressed the button for aerialists Sebastian and Sonia after being incredibly moved by the fact that 30-year-old Sonia fractured her arm during rehearsals, so 24-year-old Sebastian ended up performing the routine all by himself.

'That is the definition of courage.

You don't give up,' Simon said on stage after the emotional confetti shower.
