Year Five student Marcus took part in the Take Part Festival in Llandudno last weekend, singing to a crowd of 900 people.
The nine-year-old takes part in something called the Rock Project in Llandudno, where young people get together to play music.
Marcus enjoys singing and playing the drums. One of his favourite songs to perform is AC/DC Back in Black and he enjoys singing Lewis Capaldi songs.
Marcus said: "I wasn't that nervous singing in front of all those people. As soon as the curtain was raised I just went for it."
