Incursion dementa was formed in 1987 by two metalfriends Benny Meerstra (g) and Radboud Burgsma (b). Douwe Leeuwen (d) and Sjoerd van Slooten (g) soon joined them. After some 'vocal auditions' Benny van der Wal (v) came, saw and conquered. The band is named after the famous nasty savage-song, but due to misspelling in the tape traders circuit the i got lost and 'dementia' became 'dementa'. Incursion dementa is pure thrash, speed, fun with numerous riffs & breaks. no track is the same. The release of the first demo 'we´re just us' in 1988 got great responses from the critics .
