For anybody who downloaded the free Mike Portnoy tribute album that was posted a little while ago, I am really getting into the band Effloresce, which had a couple of songs on there. Their stuff just came up randomly on my itunes and I was like "what is this pretty cool prog metal?" I checked and saw it was from the MP tribute. My next thought was, "I wonder how long before some awful vocals come in and ruin it?" Then this beautiful female vocal begins, and I am intrigued. Then, imagine my further shock when, a couple minutes later, this same vocalist begins growling savagely. And then shifting immediately back to clean vox. Repeat this sequence a few more times.
WOW!
Admittedly, I don't listen to a heck of a lot of growling music, so maybe there are plenty of female growlers out there. I was, however, really quite impressed. The thought of a female Opeth even ran through my mind during a couple of passages, but I'm no Opeth expert so that may be a completely worthless comparison.
If you'd like to check out Effloresce, the MP tribute looks like it's still available at
https://www.spaceprog.com/ For a sampling of the growls, listen to "Sear" at 4:07 or "Sunset in the Snowdome" at 4:50. I like the growling section in the first one better but the songs are about equal. Right now they only have a 3 song EP available, but they're supposedly working on a full length release. Not much by way of youtube, but here's their myspace for "Sunset" --
