Seventy-five years ago a man with big hair and sexy moves got the nation “All Shook Up.” To commemorate the anniversary of Elvis Presley’s birth, the National Portrait Gallery’s exhibit One Life: Echoes of Elvis begins at the beginning of January. Echoes of Elvis explores the singing legend’s impact on art and pop culture through the works of artistic masters like Andy Warhol, Ralph Wolfe Cowan, Red Grooms.  Even though he is gone, this exhibit will capture the rock ‘n roll of Elvis Presley.
