Female vocals - boosting prog?

I was listening to several songs and came to the conclusion that female vocals give a different feeling in many songs and probably convert them from very good songs to masterpieces. Examples from prog metal can be seen in Suite Sister Mary (no need to mention the band) and Ayreon's Isis and Osiris (these are the first that come into my mind, sure there are a lot more)

Note: I don't mean bands that have a permanent female vocalist (Gathering etc.) which most of them are great IMO (never listened to a 'crappy' prog band with female vocalist thus far)

so does anyone feel the same? any further examples, thoughts, disagreements...

I honeslty can't say I've heard any prog with female vocals( except for SFAM). But it ihnk it could be alright

Ususally i tend to thing that girl's vocies in rock sound out of place.  Great example is Barracuda. Its a great song, and even though her voice is really strong, it would be better asa  guy.

IMHO, a female voice in any band, but particularly progressive, metal, and symphonic bands is nearly always an asset to the music.  The various Ayreon and Ambeon works are great examples (so are a bunch of collaborations Jah Wobble has done with female singers).  The Gathering, Thinking Plague, Stream of Passion, Nightwish, Renaissance, Amon Düül 2, Babe Ruth, Gong, Art Bears, Curved Air, Mostly Autumn, Iona,... too many bands to mention whose music wouldn't be the same without the women whose voices help make their music special. 

On the non-prog side, Heart, Jefferson Airplane, Kate Bush, Pretenders, Cranberries, Belly, Chicken Shack, Ramatam, Lone Justice, Rilo Kiley, SSQ, The Killjoys, The Arcade Fire, Blondie, Walls of Jericho, 10,000 Maniacs, Cowboy Junkies, Blondie, Cocteau Twins, Portishead, are all bands who wouldn't be nearly as good as they were/are without their female members.

There are far fewer male singers (again, IMHO) who really stand out for their vocal abilities than there are women.  Steve Walsh, James LaBrie,

Okay, there's two.  Not many others.

I’m not trying to be sexist but I don’t think the femaleis very well suited to prog.
