[{"role": "system", "content": "Avenged Sevenfold (sometimes abbreviated as A7X) is an American heavy metal band from Huntington Beach, California, formed in 1999. The band's current lineup consists of lead vocalist M. Shadows, rhythm guitarist and backing vocalist Zacky Vengeance, lead guitarist and backing vocalist Synyster Gates, bassist and backing vocalist Johnny Christ, and drummer Brooks Wackerman. Avenged Sevenfold is known for its diverse rock sound and dramatic imagery in album covers and merchandise. Avenged Sevenfold emerged with a metalcore sound on the band's debut \"Sounding the Seventh Trumpet\". However, Avenged Sevenfold's style had evolved by the band's third album and first major label release, \"City of Evil\", into a heavy metal and hard rock style. The band continued to explore new sounds with its self-titled release and enjoyed continued mainstream success before their drummer, James \"The Rev\" Sullivan, died in 2009. Despite his death, Avenged Sevenfold continued on with the help of now-former Dream Theater drummer Mike Portnoy, and released and toured in support of its fifth album \"Nightmare\" in 2010, which debuted on the top spot of the \"Billboard\" 200, Avenged Sevenfold's first number one debut.\n"}, {"role": "user", "content": "My favorite band is Avenged Sevenfold, what band do you like?"}, {"role": "assistant", "content": "I have never heard of Avenged Sevenfold.
