The producers' high-flying "Aireus" held forth at the Hilton Theater for two seasons, now it's their stratospheric "Night Beat." For the Wall/ Maes' team high is definitely in. Both shows starred and star the world's foremost aerialist daredevils, Russia's Flying Cranes, in a splendid mounting of their act on the world's largest indoor stage. If one has the slightest interest in death-defying athletics, ballet or show business, every effort should be made to see the Flying Cranes in "Night Beat."

Fortunately, there's more, much more to "Night Beat" than that stellar act. The show is at its best when the Flying Cranes are on stage, but its also most impressive when Trent Sherrell does his smooth-as-silk adagio act midair, when the throaty Traci Ault sings and when "Night Beat's" Michael Darrin Dancers cut loose on Benny Goodman's "Sing, Sing, Sing." When any of those four elements are on stage, "Night Beat" soars.

As the band whips "Sing, Sing, Sing" into a frenzy of swing, the zoot suited Michael Darrin Dancers sizzle through one of the hottest, most energized nightclub dance routines this side of Broadway. "Sing, Sing, Sing" is finger snappin', exuberant show-biz chutzpah at its blazing best. With costumes by Lucio Boliver that are as colorful and vivid as the number's music and dance, "Sing" is a showstopper.

The handsome Trent Sherrell glides through the air in one of the most haunting nightclub spots in memory. Sherrell has adonis good looks and an amazing athleticism metamorphosed into artistry that is - in this marvelous act - breathtaking. Sherrell makes his entrance shrouded in a monk's robes. When he disrobes, exposing his striking physical appearance and one of show-business' skimpiest costumes, there's an audible gasp from the audience. Sherrell's performance is a celebration of the human form reminiscent of the stunning High Renaissance frescos of Michelangelo.

Singer Traci Ault has one of those 40's band-singer looks missing only a Ginny Simms snood. Whether lounging seductively on a grand piano singing "I Want You Back and That Ain't Good" or moving sensuously across stage, Ault is gorgeous, sexy and sings wonderfully.

In the most incredible aerialist acts anywhere, the theatricality of the tribute to fallen heroes of World War II by the Flying Cranes defies verbal description. Poetry in motion is a much overused phrase. When applied to the Flying Cranes, poetry in motion doesn't do full justice to the majesty, extraordinary artistry and magnificent skills of these superb artists. The Flying Cranes must be seen to be believed.

Geechy Guy is "Night Beat's" gawky, off-beat comedian. Guy makes gangliness and awkwardness into an art form. When he warms to an audience and lets loose with a series of oneliners, he can be very funny.

Terry H. Gerard's lighting is exceptional. Michael Darrin's choreography and staging is first-rate, although some of this 90-minute show is too repetitive and often much too loud. But the cast is beautiful, buffed, talented and terrific, so why argue relative trifles? For all but a very few minutes, "Night Beat" is a splendid mix of athleticism and artistry and a most handsome and entertaining show-business package.

With the exception of Fridays, "Night Beat" can be seen at the Reno Hilton Theater nightly at 8. For information call 775 789 2285
