Brazilian 2wins is a music group led by Wagner and Walter Caldas.
Walter typically plays the violin and Wagner plays the ukulele. The twins grew up in Rio De Janeiro in Brazil, making their first trip to the United States about seven years ago to perform a two-minute music piece in Des Moines.
University of Northern Iowa President Ben Allen was there, liked the performance and invited the twins to study at University of Northern Iowa.
"We'd like to come, but whatever and we couldn't speak English at all," Wagner and Walter Caldas said.
The 27-year-olds are now studying music on scholarships. They are the first in their family to go to college.
"We are learning a lot and have a lot to learn," the twins said.
Wagner and Walter began playing the violin as children in Brazil. Their dad made instruments but never played any.
Initially, the pair didn't want to practice.
"Nightmare. We had a lesson once a week, and we would hide," Wagner Caldas said.
Growing up very poor, they found out they could perform for food. That's when music became more important.
The twins said they never dreamed they'd one day play for money, but Walter said money isn't why they perform.
"For me, all I want is someone to say 'You can change my life, you made me smile.' That's all I want in music."
Walter and Wagner have another year left of school. The ultimate goal is to travel around the world playing music and having fun, which is why so many people enjoy their performances.
