Buenos Aires-based imprint Unlock Recordings release the fourth instalment of their 'Collaborations' series featuring cuts from Ryan Crosson, Jonas Kopp, Guti From Downstairs and more.The stripped back aesthetic of previous 'Collaborations' vinyl-only releases have garnered some heavyweight support from the likes of Ricardo Villalobos, Sonja Moonear, Raresh and Laurent Garnier, to name a few. Gonzalo Solimano's label now returns once again, showcasing some of Argentina's most exciting talent alongside other distinguished names from the scene - further establishing Unlock Recordings' reputation for delivering high quality, jazz and dub-infused house and techno.
