William Basinski (8pm Fri-Sat at San Antonio Museum of Art, 200 W. Jones Ave.): With a jaw cut from granite and a roster of unkempt, leonine haircuts, a subway-stop look at William Basinski might not give the impression that he’s in the one-name club of American art music. Most people record to tape, using the black plastic strips to document their work on other instruments. Basinski plays the tape itself, manipulating his reels to create new work from old sounds. A Basinski joint is a long and gorgeous thing, with meaning and emotional resonance coming from the repetition of his tape loops and piano tinkering. Ronnie Cramer (11pm Fri-Sat at San Antonio Museum of Art, 200 W. Jones Ave.): Denver-based artist, musician and filmmaker Ronnie Cramer is an all-arts lifer. Active for 30-plus years in various mediums, he has been especially lauded for his experimental, independent film work. For Luminaria 2015, Cramer will unveil an animated video composition entitled simply SA, which is comprised of more than 4,000 individual watercolor paintings and acts as a virtual tour of the city. Unofficial Luminaria Experimental Music Showcase (7:30pm Fri at The Ten Eleven, 1011 Avenue B): This Friday, as an exciting and unofficial nod to the all-arts buffet that is Luminaria, dig this doozy of an experimental music showcase. A local/regional affair, the free show features six of the most interesting and inventive experimental musicians in South Texas — true boundary-pushers. We are especially excited to catch the sets from Lazy Comet’s Leonard Orozco (psych-drone), James Woodard and Mario Trejo of Grasshopper Lies Heavy (guitar loops, synth, organ) and Marcus Rubio’s More Eaze collaborating with ATX’s Amulets (atmospheric drone mixing electronic and acoustic sound).
