Peter Carlsson, sometimes misspelled as Peter Karlsson, is a Swedish vocalist and vocal arranger and producer and was a member of defunct Swedish band Carolina Liar, alongside his brother Johan Carlsson.
During his time working under Carolina Liar, fronted by Chad Wolf, the band was one of the only ones signed by Max Martin’s production company Maratone for publishing purposes and worked with him and his team on both of their albums Coming to Terms and Wild Blessed Freedom. Due to underwelming performances in charts and live tours, the band initially thought of disbanding in 2011. Eventually, members Johan, Peter and Rickard Goransson were recruited by Max Martin to become songwriters and producers under the newly-branded studio MXM Music and Productions in 2012. Peter worked and currently works as a vocal producer, contributing to many of MXM and Wolf Cousins written and produced songs.
