In addition to their One Square Mile documentary series, first reported here, married Fort Worth filmmakers Carl and Betsy Crum are tackling a project that’s inherently lighter though much more likely to result in bloodshed in public forums. The Crums are putting together a doc on “Texas music legends” (and by “Texas music,” I’m pretty sure they don’t mean only of the Pat Green variety). “Obscure or not,” the Crums say on their Facebook page, doesn’t matter. What they’re looking for are Texas artists who’ve “made a significant impact or contribution to music on a large level.” The first dozen or so names should rattle off your tongue: Willie, Ornette, Bob Wills, Buddy Holly, Lightnin’ Hopkins, Blind Lemon Jefferson, Stevie Ray, Townes, Janis, ZZ Top, Waylon Jennings, Roy Orbison, and Lyle Lovett. As for the “obscure,” well, let’s see. You’ve got the Legendary Stardust Cowboy, who was born in Lubbock but perfected the fine art of howling over horrible guitar playing and drumming to achieve legendary cult-like status in Fort Worth. You’ve got Jandek, the Houston-area recluse whose out-of-tune acoustic ramblings reportedly influenced the highly in-tune ramblings of no less a groundbreaking act than Nirvana. Who else? Hmmm. Well, there’s Pantera. “Dimebag” Darrell Abbott and company weren’t groundbreaking, but they were extremely proficient at metal music. And popular. One Texas artist whose groundbreaking qualities are not in question is Roky Erickson, mainly for his work as bandleader of the ’60s-era psych outfit the 13th Floor Elevators. Lastly, you’ve gotta get some hip-hop in there, and the undisputed epicenter of Texas hip-hop was and remains H-town, birthplace of DJ Screw, an artist who forever influenced the sound, the actual audio qualities, of hip-hop. I guess you could also throw Houston’s Geto Boys in there. Any other suggestions?
