Sommar i P1 has aired every summer since its start in 1959, and is made up by interesting Swedish-speaking persons who get free hands to create their own hour and a half long show. They get to pick their own topics and choose what music to play.
One notable host this year is Gloria Ray Karlmark who was one of The Little Rock Nine, a group of nine African American students who enrolled at the racially segregated Little Rock Central High School in Arkansas in 1957. The Little Rock Nine became an integral part of the US Civil Rights Movement.
Other hosts this year include the former Swedish Prime Minister Ingvar Carlsson, singer José Gonzalez, the former UN official and whistleblower Anders Kompass, film and TV director Johan Renck and Swedish national football team player Kim Källström.
