Yup Vina is a little posh. But Valparaisso is the next beach to the south. Very cold this time of year, need a good seafood chowder.
In Valpo there is one place called Deck00 which is out on the pier at the northern end of Valpo called Mule Baron. They've had Hawtin and Villalobos out there a few times. In Santiago there is a strong little minimal scene. Check La Feria and the trendy afterhours house in Bella Vista. Tony Mass is a resident at La Feria. Miguel Tutera is another guy, had a few releases on Eukatech go see him at Fun Tracks record store at Manuel Mont station on the metro (towards Golfe direction). Also Tom records across the road more minimal specialists.
And then yeah theres Haverbeck and a few playing hard stuff. Hard to find, and the Chilean Spanish is a ****ing nightmare - but plenty of fun to be had and fun finding it. Saludos weon!
