The list of famous musicians from the Milwaukee area is disappointingly short, but we will always have Liberace.
Wladziu Valentino Liberace was born in West Allis on May 16, 1919. A veritable child prodigy on the piano, he was already performing classical concerts in his teen years but soon put together an act that included pop, showtunes, boogie-woogie and his own unique flash. By the 1950s he had his own television show and was a top-flight celebrity around the country. He performed concerts all over the world, demonstrating an incredible mastery of his instrument and an outsized stage presence beloved by his fans. Here's a great sample of his performing ability: https://www.youtube.com/watch?v=q9nO9Ro_kd4
Throughout his life, Liberace was a gay man who tried to keep his orientation a secret. He was dogged by rumors and gossip and often threatened to sue publications spreading anything about his personal life. Despite this, his over-the-top style and showmanship made him into a gay icon for the ages. He died of AIDS-related complications in 1987.
More recently, Liberace's life was the subject of a film titled Behind the Candelabra starring Michael Douglas (as Liberace) and Matt Damon. He will always occupy a special place in the hearts of Milwaukeeans.
