Robbi Robb has been fronting the South African band Tribe After Tribe for over two decades, raising awareness of global social issues with his potpourri of multicultural rock music as a soundtrack. The latest venture from this unit is the 15-track M.O.A.B., an album that boasts thirteen different musicians making the most of the vast arsenal of styles at their dispose. From the flannel-shirt stomp of “Holy City Warrior” and “Shock and Awe” to the native sounds emanating from “World Drum” and “Lament,” this outspoken collective returns after a lengthy hiatus sounding like a cross between Peter Gabriel and Sepultura, adorned with a well-rounded smattering of hard edged world class rock that fans of the more adventurous sounds of the ’90s are bound to embrace.   www.myspace.com/tribeaftertribe –Mike SOS
