BEHIND BARS: Behind, next to, between...whatever you want to call it, there among the watering holes on Fourth Avenue between Seventh and Eighth streets is the Winsett Park stage, where the live music plays on every Thursday starting at 7 p.m. On July 25, the usually raucous sonic uprising takes it down a notch with classical guitar and acoustic grooves by Lisa Reilly and Co., Beyond Words and Annie Hawkins. Bring the family and find a comfortable place under the stars for this free event. Call 624-5004 for information. FILM TRIP: Get reel with your fellow filmmakers (there seems to have been a recent influx of them) at a free meeting of the minds. The Tucson Association of Independent Video and Filmmakers meets at 1:30 p.m. Saturday, July 27, at The Screening Room, 127 E. Congress St. There will be a short business meeting (so you can arrive fashionably late if you're a newcomer), followed by a rough-cut screening of selected members' works-in-progress. Call Beverly Seckinger at 621-1239 for information. MICRO-BROUHAHA: Some big problems have really small solutions. Microscopic, in fact. At least, that's what Dr. Teruo Higa, an agriculture prof at the University of Ryukyus in Okinawa, Japan, contends. Higa is credited as the discoverer of EM, or "effective micro-organisms," a scientific innovation for a rotten, stinking planet. EM offers a new approach to soil revitalization, composting, pro-biotic livestock feeding, household cleaning and, in short, "for anything smelly." If you're the kind of person who willfully sits through infomercials, you might as well hear him out in EM Technology and a New Industrial Revolution, a free lecture from 7 to 9 p.m. Saturday, July 27, in the UA Social Science auditorium, south side of the mall west of Old Main. Maybe you'll save the planet. Call 629-9301 for information. GLASS HOUSE: Interior Motives II, an annual gathering of artists showcasing the best in contemporary art glass for the home, continues through August 31 at Philabaum Contemporary Art Glass, 711 S. Sixth Ave. You've never seen sand like this before: innovative creations blown into all shapes and sizes, many of which actually have a purpose. Gallery hours are 10 a.m. to 5 p.m. Tuesday through Saturday, with glass-blowing demonstrations usually given between 10 a.m. and 2 p.m. Call 884-7404 for information and a confirmation of the day's demonstration schedule. WATCH THE BLUEGRASS GROW: The monthly Desert Bluegrass Association jam session gets underway at 2 p.m. Sunday, July 28, at the Southwest Center for Music, 2175 N. Sixth Ave. If your musical talents aren't properly appreciated in the living room, this may be the group for which you've been looking. Musicians of all levels are welcome to attend, and there's always room for an appreciative audience. Call Bonnie at 296-1231 for information.
