Look beyond the Top 100 DJ hype and you'll find that underground dance music is still populated with small crews that work tirelessly in service of a simple goal: to build a joyful society of music lovers around a clear set of aesthetic principles. Nemo Ripoll and Castro Moore, this week's RA Podcast guests, have gone further than most to achieve these ends. The physical headquarters for these efforts is the Sound Metaphors record shop in Kreuzberg, Berlin. In non-lockdown times, the small, impeccably-curated store is a hang out for a certain strand of Berlin record heads—those interested in the scruffier side of house, Balearic, disco and other genres, but perhaps more drawn to the fun, laid-back social scene that has sprung up around the store and other related ventures. This mix of nerdiness and insouciance comes through full force in the HAVE A NICE DAY (H.A.N.D.) parties thrown by Nemo and Castro, a roving affair in which the likes of Chee Shimizu and Idjut Boys throw down in clandestine lofts on a custom soundsystem. Then there's the family of Sound Metaphors imprint, including sub-labels like Missyou, Thankyou and Blessyou, serving up everything from cheeky edits to obscure and essential Detroit house with a wink and a smile. This cluster of underground activities truly comes together in Nemo & Castro's DJ sets, which feel like proselytizing missions for the joy of diva house, hi-NRG and other oft-discussed but rarely-rinsed genres. Their classic approach, fueled by an avid study of legendary US gay clubs in the past, has made them sure-shot bookings at Panorama Bar, Berlin Atonal and any other setting where you need a DJ set that follows in the true spirit of excess and hedonism that all of this was built on. This historically reverent exuberance is palpable on their RA Podcast, which sees the duo string together a series of big moments through the arpeggiated DNA of the past.
