Mates of State is one band that fits this description.
I believe it was Cannonball by the Breeders, if memory serves.
Just a few examplesUnholy (Finland) - Growling male vocals with limited use of female vocals in the The Second Ring of Power, Rapture, and Gracefallen albumsNightwish (Finland) - Mostly clean female vocals, with a fair amount of clean male vocals usedAshes You Leave (Croatia) - Primarily clean female vocals with intermittent male growling vocalsHammers of Misfortune (United States of America) - Clean male vocals, clean female vocals, often sung in conjunction with each other. Some songs from the debut album, The Bastard, have the female vocals backed by growling male vocals sung in conjunction.Theatre of Tragedy (Norway) - Female lead singer with clean vocals backed by a male singer in the Theatre of Tragedy and Velvet Darkness They Fear albums. After these two, they strayed away from Metal. This is the band which started the often-imitated "Beauty and the Beast" male/female vocals.Girlschool (United Kingdom) have several songs they did collaboratively with Motorhead, featuring the vocalists of both bands singing.Funeral (Norway), but only on the Tragedies album. Tristesse featured all male vocals, and In Fields of Pestilent Grief was solely female vocals.Cradle of Filth (United Kingdom) is a male-fronted band, but often features guest female vocalists.Shroud of Bereavement (United States of America) - Growling male vocals, clean female vocalsThe Sins of Thy Beloved (Norway) - Started off essentially as a Theatre of Tragedy knockoff. Growling male vocals, clean female vocalsTristania (Norway) - Mostly growling male vocals and clean female vocals. Some clean male vocals used in some songs. Also uses a choir composed of both male and female vocalistsSirenia (Norway) - Started by the founder of Tristania. Same description.After Forever (Netherlands) - Mostly growling male vocals mixed with clean female vocals.Epica (Netherlands) - Same formula as After Forever, founded by the person who founded After ForeverWithin Temptation (Netherlands) - Their debut album, Enter, featured growling male vocals and clean female vocals, in a simlar vein to earlier Theatre of Tragedy and The Sins of Thy Beloved. Later albums went almost exclusively to female vocals.Disrupt (United States of America) - Maybe a bit questionable of an entry for a question about Metal bands. Disrupt is a Crust Punk band (sharing a common heritage and many similarities to Grindcore). Vocals are primarily shouting male vocals, but several songs feature a female singer who practically screams her lungs out, as well.
the band consists of siblings Marc Costanzo (vocals, guitar) and Sharon Costanzo (vocals, bass).
