ZZ Top is an American hard rock band formed in 1969 in Houston, Texas. The group members are Billy Gibbons (guitar, lead vocals, harmonica), Dusty Hill (bass, vocals), and Frank Beard (drums, percussion).

They hold the distinction of being among the few rock bands still composed of its original recording members for nearly 40 years and until September 2006, the same manager/producer, Bill Ham.

They reached the peak of their commercial success in the 1970s and 1980s, scoring many hit songs during that era, but they remain together today and are still touring and releasing albums. ZZ Top was inducted into the Rock and Roll Hall of Fame on March 15, 2004. Summarizing their music, Cub Koda wrote, "As genuine roots musicians, they have few peers; Gibbons is one of America's finest blues guitarists working in the hard rock idiom ... while Hill and Beard provide the ultimate rhythm section support." Their song lyrics often feature sexual innuendo and humor. Gibbons and Hill are also famous for their custom guitars, many of which were co-designed by Gibbons with master luthier John Bolin of Bolin Guitars. Hill requests that his basses have a similar neck profile to the 1950s Fender Precision Bass he used extensively in the early days of the band.

Nearly as well-known as their music is the group's appearance: Gibbons and Hill are almost always pictured wearing sunglasses (a nod to their 1979 song "Cheap Sunglasses"), similar if not matching clothing, and their trademark chest-length beards (Ironically, in spite of his own surname, Beard almost always sports just a mustache). In 1984, the Gillette Company reportedly offered Gibbons and Hill US$1 million apiece to shave their beards for a television commercial but they declined, stating "We're too ugly without 'em".

The band were honorees by Billy Bob Thorton at the second annual VH1 Rock Honors on May 24, 2007. Nickleback performed a rendtion of Sharp Dressed Man as an introduction. The same show also included Ozzy Osbourne, Genesis and Heart.

On November 1, 2007 the band taped a live performance at the Nokia Theater in Grand Prairie, Texas, reportedly for a live DVD release.

ZZ Top's most recent high-profile was a performance at the 2007 Orange Bowl game in Miami. They also performed in 2008 at the Auto Club 500 NASCAR event at Auto Club Speedway in Fontana.
