Gymnastic troupe Spelbound and street dancer Tobias Mead were named as the first two acts to go through to this year's Britain's Got Talent final.
The young acrobats scored the highest number of viewers' votes among the eight acts to perform in the first live semi-final of the ITV show -- securing an automatic place in the final.
Judges Piers Morgan, Amanda Holden and Simon Cowell then chose Mead over fellow runner-up 14-year-old singer Olivia Archbold to take the second final spot.
Forty semi-finalists will be whittled down in shows each night this week until the remaining 10 battle it out in the live final on Saturday for a chance to appear at the Royal Variety Performance.
Spelbound, the last of the eight acts to perform, won high praise from the judges during last night's show for their daring and intricately choreographed routine.
Holden said she wanted to see them in the final, adding: "It didn't disappoint. It was high-voltage excellence."
Morgan declared it "one of the most extraordinary routines". Cowell labelled the level of detail in the routine "incredible", stating: "This is what this show is all about, finding undiscovered talent and you are that."
Fellow finalist Mead also attracted plenty of plaudits from the trio, with Morgan declaring his performance "one of the most creative and inspired dance routines we've seen on the show".
Holden added: "Absolutely brilliant, innovative, clever, keeping those brilliant fluid movements."
Cowell said: "It was really, really smart. You know we have a lot of groups on here, but what you did on your own was really creative, I thought it was outstanding."
Archbold, who sang What If by Kate Winslet, was told by Morgan she sang with "remarkable" maturity.
Holden said: "It was a very confident performance. You should be proud of yourself."
Some of the acts on the first live show split the judges.
Kevin Cruise's medley of hits on board the Fishy Rose was buzzed by Cowell, who said: "The only ship I wish he was on was the Titanic."
But Morgan said: "Every song choice, every dance move, every tassel wiggle, everything was designed to cause Simon Cowell maximum discomfort and I loved it."
