The Fabulous Soul Shakers proudly proclaim that ?this ain?t no oldies group,? and, 30 seconds into their finger-popping take on the likes of ?I Want a Love I Can See? or the aching joy of ?I Found a Love,? you?ll agree. These five young men, three of them out of Harlem and all dressed to the nines, present the sounds of the city in magnificent harmony. That the tunes they perform are the stuff of glories past has nothing to do with nostalgia?and everything to do with great rhythms and vocals. The group features Ryan Shaw, 27, who snared a Grammy nomination this year for his solo cut, ?I Am Your Man.? Then there?s Jason Cousins (a/k/a J-NYSE), 23; Richard ?Terrelle? Tipton, 24; Craig ?Suga? Stagg, 31; and Bryant ?Sparrow? Washington, 29. The music was new to them until manager Pete Rosenbaum, searching for that sweet soul sound, put them together a few years ago. The trick is to catch them in the act. They?ve played everywhere from McCarren Park Pool to Carnegie Hall and B.B. King?s. Keep an ear out?it?s worth the wait.
