Andy Grammer may have shot to fame in 2012, but he honed his craft as a street performer in California's Santa Monica.

Eventually, he came to the attention of record producers, who made him a star and ensured he got airplay on some of the world's biggest radio stations.

Grammer is best known for his first two singles Keep Your Head Up and Fine By Me, which show off his brand of pop songs that blend heartfelt lyrics with unforgettable melodies.

Guests at St Louis hotels can see this for themselves if they go along to the Old Rock House on April 11th, where the musician will take to the stage to play all his latest tracks.

Tickets cost a $20 flat rate fee, which fans will agree is a bargain for an artist of this calibre.

Residents of the Millennium Hotel St Louis will have no trouble getting to the Old Rock House, as it is just 16 minutes' walk away via South 4th Street or a ten-minute bus ride on the number 40 service.
