Random notes on popular music, late summer, 2018: If you have to ask me about Eclair Fifi one more goddamned time, then no trip to the starry black infinity after show party for you, bucko. She’ll be in concert on Friday, Aug. 24 at Sister (407 Central Ave. NW). More precisely, the type of music generated by Clair Stirling—under the aegis of an arhat ardently using turntables, samplers and more modern equipment like Audio Technica ATH-M60x monitor headphones and a lot of virtually positioned twisty nobs—is by turns haunted and haunting. With roots in the Chicago variety of house buried deep in her brain, you’ll come away pulsating like a bad ghost too. There may be small tubular containers of bass drifting through the air. Let them pass through you. 8pm • $10 • 21+.
