Concert, chantfest, musical group meditation, a yoga class in melody . . .

How best to describe a live performance by Snatam Kaur and her band?

It’s all of these things and more. Seated center stage, Snatam is an angelic presence, dressed in traditional Sikh attire, bejeweled dress, white turban and veil. She’s a diminutive woman, barely five feet tall, but possessed of a voice that could wrest tears from a stone gargoyle — crystalline and radiant, redolent of the simple yet powerful truth of the heart.

That voice has made her one of the top selling artists in the field of world sacred music. Amid the swelling ranks of devotional divas and mantra mamas, Snatam stands tall.
