Beyoncé's lighter skin color and costuming has drawn criticism from some in the African-American community. Emmett Price, a professor of music at Northeastern University, wrote in 2007, that he thinks race plays a role in many of these criticisms, saying white celebrities who dress similarly do not attract as many comments. In 2008, L'Oréal was accused of whitening her skin in their Feria hair color advertisements, responding that "it is categorically untrue", and in 2013, Beyoncé herself criticized H&M for their proposed "retouching" of promotional images of her, and according to Vogue requested that only "natural pictures be used".

In the new commercial climate glam metal bands like Europe, Ratt, White Lion and Cinderella broke up, Whitesnake went on hiatus in 1991, and while many of these bands would re-unite again in the late 1990s or early 2000s, they never reached the commercial success they saw in the 1980s or early 1990s. Other bands such as Mötley Crüe and Poison saw personnel changes which impacted those bands' commercial viability during the decade. In 1995 Van Halen released Balance, a multi-platinum seller that would be the band's last with Sammy Hagar on vocals. In 1996 David Lee Roth returned briefly and his replacement, former Extreme singer Gary Cherone, was fired soon after the release of the commercially unsuccessful 1998 album Van Halen III and Van Halen would not tour or record again until 2004. Guns N' Roses' original lineup was whittled away throughout the decade. Drummer Steven Adler was fired in 1990, guitarist Izzy Stradlin left in late 1991 after recording Use Your Illusion I and II with the band. Tensions between the other band members and lead singer Axl Rose continued after the release of the 1993 covers album The Spaghetti Incident?

The western section of the state is part of the Appalachian Mountain range. Among the subranges of the Appalachians located in the state are the Great Smoky Mountains, Blue Ridge Mountains, Great Balsam Mountains, and Black Mountains. The Black Mountains are the highest in the eastern United States, and culminate in Mount Mitchell at 6,684 feet (2,037 m) the highest point east of the Mississippi River. Although agriculture still remains important, tourism has become a dominant industry in the mountains. Growing Christmas trees has recently become an important industry as well. Because of the higher altitude, the climate in the mountains often differs markedly from that of the rest of the state. Winter in western North Carolina typically features high snowfall and subfreezing temperatures more akin to those of a midwestern state than of a southern state.
What is the name of the highest point east of the Mississippi river?
A:
Mount Mitchell
