In May 2013, In Solitude visited Vasaborgen, the historical castle in their hometown Uppsala where the Sture murders took place, and recorded there a special session for the swedish television, which included "A Buried Sun" and their cover of the Cortex song "Jesus I Betong", as well as an interview with each member of the band. At the end of October, PSL broadcasted it as a three-part miniseries called “On the Dark Side of Uppsala” and later on in November, due to fans demand, an English subtitled version was made available.
