If you love being on the pulse of bourgeoning music, mark your calendar for Tuesday to Friday next week. Trans-Pecos, DIY baby from booker Todd P, and ground zero for avant-garde music off the L train, is transforming into a beat lair. Nicolas Jaar, NY-based composer, electronic musician, and head of record label Other People, will be curating the space’s sounds four days in a row. Having headlined the Brooklyn Electronic Music Festival in 2012 and more recently sold out Terminal 5 with his psychedelic electro group Darkside, Ridgewood is lucky to have him.
