Maybe it's some mysterious cosmological force that, outside the movies, only allows storybook endings to happen around Super Bowl Sunday. However, this particular story had nothing to do with the undefeated New England Patriots allowing the 11th-hour touchdown pass that gave the underdog New York Giants one of the biggest upsets in sports history.

This came from right here in Houston, in a quadrant of the city most people only know from rap lyrics and local news reports dominated by flashing emergency lights and crime-scene tape — if they even spare a thought for neighborhoods like Trinity Gardens at all, that is. It happened at a beleaguered school threatened with closure due to low test scores for several years now, and most recently in the news when a 2007 Johns Hopkins University study labeled it a "dropout factory."

Last Friday afternoon, around 30 former members of the Kashmere High School Stage Band gathered at the near northeast side school for a tribute concert in honor of their former band director and father figure, Conrad O. "Prof" Johnson. Under Johnson's baton, the Kashmere Stage Band dominated local, regional and national band competitions more thoroughly than the Patriots have recently dominated the NFL, winning 42 of the 46 contests it entered between 1968 and Johnson's retirement in 1977.

The band room at Kashmere contains so many trophies — some as big as six feet tall — they've long since spilled from atop the uniform lockers lining one wall onto the floor. Warming up on his tenor saxophone, 1973 KHS grad and former drum major Bruce "Rick" Middleton said Johnson was "more like a friend to the students in the band, but he was a firm leader. He treated the students like musicians."

Johnson, an alto sax player, wrote or arranged all of the Kashmere Stage Band's music and often showed his students the intricacies of composition and orchestration during after-school lessons at his home. His willingness to incorporate popular music of the time like James Brown and Sly & the Family Stone into the band's repertoire not only endeared him to his students, contest judges and even Count Basie (who once said Johnson's was the best school band he'd ever heard), it gave the Kashmere Stage Band an unexpectedly long shelf life.

As hip-hop became popular, DJs like Houston-born DJ Premier of Gang Starr realized the meaty grooves and sizzling horn licks Johnson devised for his band were ideal sampling material. The band thus became known to listeners like Eothan Alapatt, who told the assembled Kashmere students, faculty and alumni on hand Friday afternoon that listening to Houston rappers Scarface and the Geto Boys during his New Haven, Connecticut, childhood indirectly led him to the Kashmere Stage Band. (In those days, school bands often recorded albums as fund-­raising tools; the Kashmere band did eight.)

"I wanted to know everything that created the hip-hop I loved so much," said Alapatt, who has released several Kashmere Stage Band albums and remix 45s, plus 2006's double-disc Texas Thunder Soul anthology, on his Los Angeles-based label Stones Throw and its subsidiary Now-Again.

"So I started digging for funk records," Alapatt continued. "After a few years of trying to go deeper and deeper, buying the rarest and most regional private-press joints that lined the crates of all the producers and DJs I knew and respected, I found the Kashmere Stage Band."

Alapatt then yielded the stage to the present Kashmere Stage Band, with director Adran Tyler on bass guitar, who warmed up the crowd with marimba-heavy Latin shuffle "Blue Bossa." The opening was a little stiff and what American Idol judge Randy Jackson likes to call "pitchy," but the smallish ensemble — about a third the size of the alumni band — built up a nice head of steam by the end and received a warm reception from the full auditorium.

"We're doing a lot of rebuilding at this point," Tyler, in his first year as Kashmere band director, said later. "That's why I'm glad they came here, so [the students] can see what they're capable of. These people went to the same school, walked the same halls and they were able to do all these outstanding things."

Introduced by current KHS principal Dr. Charlotte Parker, the alumni band filed onstage and began with a slow electric piano riff that built into the huge, brawny bebop/funk number "Zero Point." They followed with "Kashmere," written by Johnson, later sampled by DJ Shadow and featuring a long, limber solo by Middleton and some delicious drum breaks from Craig Green — who, as it turns out, was Adran Tyler's band director at southwest Houston's Johnston Middle School. By this point the alumni were eating it up, applauding after solos and shouting their approval. The students were a little more reserved, but for the most part were attentive and respectful.
