I feel your pain n80. From the moment I started listening to music I was always drawn to the nuances of the male singer. From Robert Plant & Ian Gillan, later obsessed with Frank Zappa, Captain Beefheart & my favourites to this day, Lou Reed, Neil Young, Kurt Cobain, Mark E Smith. I’ve probably forgot a few.
But on the subject of Female vocals, I’m generally not a fan, but I think that’s mainly down to the soppy crap they’re singing. I hear all the time Diane Krall, just sounds like insufferable whining to me. But a band I love, who I think are criminally underrated is Massive Attack and they have introduced me to numerous stunning female vocals. It’s obvious to reel off the examples on the first 3 albums, but I would recommend the less acclaimed 100th Window and Heligoland. Sinéad O’Connor, Martina Topley-Bird, Hope Sonderval. Chilling vocals & great music.
