Imelda May - Inside Out. As respects the music Imelda performs, she does not have a genre-restricted repertoire; any one song can have elements of more than one genre in it. She does rockabilly -- for which she was warned that she would go nowhere for it --; she does swing/cabaret; jazz, and R'n'B, too. She is a very eclectic performer. Thank you, Lally Pegorini, for putting me on to her music.
