"Johnnyswim" is a Los Angeles based, folk, soul, blues, pop music duo consisting of singer-songwriters Amanda Sudano and Abner Ramirez. The duo formed in 2005 in Nashville, Tennessee. Ramirez trained as a musician at Douglas Anderson School of the Arts in his native Jacksonville, Florida. Sudano spent summers touring the world as a backing singer for her mother, disco icon Donna Summer. Ramirez and Sudano first met after Sunday service at a church in Nashville, Tennessee.

Four years later Sudano attended a songwriting workshop held by Ramirez and became interested in writing songs with him. The pair formed a songwriting partnership and called themselves Johnnyswim.

The duo married in 2009.
