There are currently a few bands with the name avantgarde, regardless of how it is actually spelt. One well-known band is an indie rock band from Spain http://en.wikipedia.org/wiki/Avantgarde_(band) and another is a booming rock band from Brunei. Brunei's Avantgarde consists of Syaeful (vocals, songwriter, composer), Sofi (drums), Yus (guitar), Erul (guitar), Jeff (bass) and the newest member, Mey on keyboard.
