Mortífera were a female fronted Thrash/ Speed Metal band. Formed in Amadora, Lisbon in early 1987 when Filipe Gonçalves drums invites Ricardo bass and Nan-Jô guitars. In September 87, Filipe receives an invitation from one of the most rounds bands back then, STS Paranoid. Filipe accepted the invitation and Mortífera is on standby. With the end of STS Paranoid in November 1987, Filipe calls the two former members but now with the addition of a female vocalist, Lena on April 1988 and in October a 2nd guitarrist, Rui. In January 1989 Nan-Jô leaves the band and Miguel replaces him. The band plays their first gig on April 23rd 1989 at the Parque Central in Amadora and their 2nd gig on the same month, 29th in Almornos, Sintra, with Procyon and Massacre (replaced Braindead). Mortífera recorded a 2 track demo tape ("Deadly Fields" and "Death Train (instrumental)") on their rehearsal/ basement with a multitrack recorder, but as the result was not the best and also for monetary reasons, the demo turned out not to go ahead. In May 13th they played in Silvares, Fundão. On July 22th the group played live again, in Massamá, with Massacre and Necrophiliac. After the concert in Massamá started a certain instability between the two guitarrists and the rest of the group. Both Miguel and Rui speak to leave the band five days before the last concert, that held in Fogueteiro, September 16th 1989 with The Coven, N.A.M. and Ramp. The group splits and Filipe joins V12 and Ricardo joins Ramp.
