Equal parts automotive exhibition, fashion show, and concert, GM Style was unlike most runway events.
Maroon 5 were joined by Grammy-winning R&B songstress Mary J. Blige and rock-rapper and local hero Kid Rock, but the cars were the stars of this show.
While the performers did their thing, General Motors was giving the stylish audience a first look at its Chevrolet E85 Hot Rod and Camaro convertible concepts, as well as 17 other offerings.
GM Style was held in a massive, climate-controlled pavilion on the Detroit River, just east of GM's global headquarters. It came on the eve of the opening of the North American International Auto Show's press preview days.
Blige, who celebrated her 37th birthday a day earlier with a surprise dinner with her father at a Detroit restaurant, strolled into the interview area ahead of the event in an ensemble that included knee-high Alexander McQueen boots.
Rock, born Robert Ritchie in nearby Romeo, Mich., was similarly impressed with GM's collection. He owns a 1962 Impala among other vintage autos, but said his everyday vehicle is a Cadillac Escalade.
Rock wore a sweatshirt with ''Detroit'' emblazoned on the front ''so I can remember where I'm at.''
His Made in Detroit fashion line was shown at GM Style, as were looks by Marciano, Kevan Hall, and the William Rast Denim Collection by Justin Timberlake.
GM executives mingled during the pre-show period with the likes of NASCAR driver Jeff Gordon, retired NFL star running back Jerome Bettis and actor and singer Nick Cannon in a cramped cocktail area.
GM Style kicked off with Blige walking purposefully the length of the runway all the while belting out her new hit ''Just Fine.'' When she reached the end of the runway, she waved hello to those in the front row — GM CEO Rick Wagoner and Detroit Mayor Kwame Kilpatrick, among others.
Blige gave the crowd two more songs, and male models sporting hip-hop mogul Russell Simmons Argyle Culture collection made their way down the catwalk. Simmons himself appeared at the end of Blige's set to slap hands with his models and receive a warm ovation from the crowd.
As the opening guitar riff of Maroon 5's set began, six sunglasses-wearing models dressed in Mark Zunino assembled before Levine and the band, then headed down the runway followed closely behind by a shiny Saturn Astra Tuner concept.
In most fashion shows, the designer ends the show by walking down the runway to applause, and GM Style was no different — in this case it was Ed Welburn, GM's vice president of design.
