A very fair point. However, you have to take into account, when someone hears your song, sees your band perfrom live, or sees you do an interview, you can't expect that their going to run to your web site and read your bio. And even if they did, 99.9999% of the planet has no idea who Carcass, Spiritual Beggars, Armageddon, Witchery, Eucharist and Dismember are. The fact that the guys in the band have the pedigree that they do means nothing to the people who market the band. As a musician, you want people to remember you when they see you/hear you. If Angela makes that happens, than bonus points for her.
I'd also say to those who slag Angela, she's done nothing to commercialize the sound of the band. Her vocals are pure Death. If you have a problem with the musical direction of the band, lay the blame where it belongs, at the feet of the folks who right the music.
