Ruby Empress first caught our eye (or rather, our ears) with the release of their easy-flowing indie debut “Deluca.” Four months later, the Swedish foursome is back with “Strung Out,” a disco groove that’s just as psychedelic and trance-inducing as its title implies.

With twangy guitar strums, fuzzy vocals that muffle intimate lyrics and warm, oozing production, it’s the type of song you’ll catch yourself hearing something new out of with each listen. The jazzy, infectious number is more than enough to build up hype around the group’s debut EP, which drops in October.
