Keeping the wheels turning on Hidden Gems and pulling more and more psychic diggers into the fold. This week the honors fall to Zak Olsen, the Aussie indie utilitarian who crops up in quite a few RSTB faves, to be honest. From the fractured pop ooze of Hierophants to the crushing grooves of ORB, Zak has done time in The Bonniwells, The Frowning Clouds, and keeps time in his own solo work as Traffik Island. The latter’s work caught my ear a few years back with a spot-on deep-dive into loner folk, but of late the band has embraced an aesthetic of psychedelic beat driven on an engine of Library Music funk. Zak gives some background on California garage band Public Nuisance and how their Nuggets-era works came into his life. Check out Zak’s take on the band’s works below and head to Flightless for the latest Traffik Island thumper.
