According to the Vort’n Vis notes Frederic Driessens (local grind/death/noise fanatic; did a series of compilation-tapes under the name Possessed By Death) arranged for these bands to come to the Vort’n Vis. Practically speaking, things were organised by Davy Bauwen (‘Edgecrusher’ vocalist) – who had to go rent mikes in the local municipal youthcentre e.g. Tom Bordeaux (‘Striker’ guitarist) and some other shitworkers attended the bar…
‘Impiety’ is a black/death metal band from Singapore. They state ‘Bathory’, ‘Possessed’, ‘Morbid Angel’, ‘Venom’, etc. as their influences. On their website, one can read that they “desecrated the Vort’n Vis with Dutch desecrators ‘Pentacle’ and French BM supremacist ‘Celestia’!”: Skullfucking Euro Armageddon Tour 2000 => 27 May – Vort’n Vis HellPub, Ieper, Belgium. Frontbeast ‘Shyaithan’ (Muhammad Ariffeen Deen) (bass/vocals) is the constant factor. On the CD Skullfucking Armageddon, recorded spring ’99, the guitarist was ‘Fyraun’ and the drummer ‘Dajjal’. Judging from the photos, they had a seperate vocalist here…
‘Pentacle’ play black/death metal from Bladel (near Eindhoven, The Netherlands) recorded their album …Rides The Moonstorm in April ’98 with Wannes Gubbels (bass/vocals), Marc Nelissen (drums) & Mike Verhoeven (guitar).
‘Celestia’ (black metal), from Avignon (France), were ‘Fureïss’ a.k.a. Franck (guitar), ‘Noctu Geiistmortt’ (bass/vocals; runs the label Drakkar prods) & a drummer. A tape, entitled A Cave Full Of Bats (their mini-album from ’99) / Live Vort’n Vis – 27/05/00 was released in Portugal and Brazil (2001); “limited to 666 copies”…
