The Gap Band was an influential American R&B and funk band that emerged in the late 1970s. Comprised of three brothers, Charlie, Ronnie and Robert Wilson, the band's distinctive sound was marked by synthesizers, percussion, and the powerful lead vocals of Charlie Wilson. The Gap Band became significant for hits like "You Dropped a Bomb on Me" and "Outstanding," and their combination of funk and electronic music elements significantly contributed to the development of 1980s electro-funk. Their influence can be seen in numerous samples used in hip-hop and R&B music today.
