What is "wah!"

'''Wah! ''' (pronounced WAAH) is a U.S. band performing and creating music for the New Age and yoga market. The female lead singer Wah! (whose legal name is Wah Devi) and the band’s name are synonymous.

Wah!’s mystical relaxation music CD, Savasana, has sold over 50,000 units worldwide and continues to draw attention in the yoga community and beyond. Wah!’s music is often compared to that of Sade, Zero 7 and India.Arie, but her latest releases (such as Maa) reflect the gritty dance grooves of her live performances.
