![]() Summer Guide index SKYROCKETS IN FLIGHT How Melrose Pyrotechnics blows up Chicago's skies
For most of us summer is--in theory, at least--a time for relaxation,
contemplation and maybe even a little vacation. For the folks at Melrose
Pyrotechnics, it's like all the year's holidays, quadrupled, and
packed into the first week of July.
As one of the nation's largest "display" companies, Melrose produces
around 80 percent of its business--more than 800 fireworks shows--during
the week of July 4, handling everything from the city's July 3
Lakefront extravaganza to WXRT's Memorial Day show to smaller shows for
more than thirty suburbs. And that's not to mention regular commitments
to sporting teams, including the White Sox (with whom they've worked
since the 1950s) and the NASCAR circuit.
"It's busy, busy, busy," says Bob Kerns, director of sales for
Melrose. "Big shows, like the July 3 show, are computer-choreographed
and computer-fired. We have four barges tied to the Monroe Harbor
breakwall and it's all run by controller, and we have people out on the
barge, but it still takes three to four days to get everything in
place."
In fact, setting up Chicago's Independence Eve fireworks actually takes
a full year. "The day after the show ends, we start on next year's,"
Kerns says. At least part of the process involves designing how the show
will look, which requires precise measurements--from how quickly the
firework shell leaves the ground to when it fires in the sky. "Say you
want something blue by the time you hit the word 'blue' in a song,"
Kerns says. "You don't want to have orange up there. We have to test
everything, even products we've used before."
Thus the company's locale--an industrial park in Kingsbury, Indiana.
"We don't have too many close neighbors," Kerns says with a smile in
his voice. "It's good for us because we do need to have an area like
that to test."
And there's even more testing as fireworks displays have taken off in
recent years. Kerns says every year the company finds more demand, from
store openings to weddings: "A lot of communities find that during
festivals, when there are fireworks the attendance levels are a lot
higher," he says. But Melrose isn't riding a new wave--the company has
been around, in some form or another, for more than 100 years.
Over time the constantly shifting fireworks technology has increased the
sophistication of their shows, Kerns says. And, the products aren't
just from China anymore. "We import from eight different countries. The
Spanish and French [products] are good at lower-level fireworks,
products that begin showing their color at ground level and going up
one-hundred-fifty to two-hundred feet. Aerial shells go up three-hundred
to twelve-hundred feet, so that way you're filling the whole volume of
sky."
If working with fireworks sounds fun, well, it is, Kerns says. But the
job is something you have to enjoy doing--designing fireworks can be
repetitious and requires a flair for drama. "You want to develop the
show like a rollercoaster, so you go up and back down to mood music or
if there's no music, you still need to build intensity so the ending is
the high point," he says.
Of all the shows Melrose does, however, Kerns notes that Chicago's July
3 fireworks are wholly unique. "With most computer-fired shows,
everything is done with taped music. We get the music into the studio
and then can go in and place event positions in the computer--tell the
computer when you want what type of thing to appear. That creates a
firing table, or script," Kerns says.
"For Chicago's fireworks, we use a tape to develop the table, but the
day-of it's a live performance, so the conductor has to listen to the
taped music in ear pieces and get the orchestra to perform in sync with
what he's hearing in one ear on the tape," Kerns says. And it isn't
as if someone learns it once and then has the hang of it. "I think
it's been a different conductor every year. But they do a good job
keeping time," he says. "That makes it a whole different
experience."
