I enjoyed Imelda any years ago when she was in her rockabilly phase fronting her band, along with her husband/guitarist.
Jeff Beck's video honoring Les Paul,showcases her band which she does fabulous covers of standards from the 40's.
Her solo efforts afterwards didn't hold my interest when I tried "Love Tattoo"
Imelda however, is in a small rare group of singers who actually sing,and doesnt scream at the top of her lungs.
