The Cardiff band, Calling Apollo, released their first record, “Hunter | Gatherer” with producer Romesh Dodangoda to rave reviews. The lead single, "Monsters", was described by Alt Corner as "a song I can see a thousand fans screaming their lungs out to at the end of a show".

They followed up with the first of a 2-part release, “The Great Depression: Act I”, with producer Todd Campbell. The record explored the political attitudes in 1920s USA and how they mirror today’s attitudes here in the UK. The lead single, "Clone City" broadcasted on Scuzz TV and when Alex Baker from Kerrang! Radio played the track on his radio show, he described the band as "Rousing, beautiful and just huge." In February 2017, they released their follow-up single, The Wars.
