UMUR
Alterations is the 2nd studio demo tape by Danish thrash metal act Invocator. The demo was released in 1989 and is a self-released affair. While the original tape version of the demo is probably very hard to track down, Alterations was made available on the Early Years (1994) compilation where the band´s first demo tape Genetic Confusion (1988) was also featured.
The 4 tracks on Alterations are technically challenging death/ thrash. We´re talking high quality and fiercely aggressive thrash metal here. Tempo changes, breaks, breakneck speed soloing and a caustic vocal delivery. Both Occurrence Concealed and The Persistence From Memorial Chasm appear in re-recorded versions on the debut album Excursion Demise (1991) and the Alterations track appear in a re-recorded version as a bonus track. The only track from Alterations that doesn´t appear on Excursion Demise is Pursuit Of A Rising Necessity.
The sound quality is excellent considereing that this is a demo tape from 1989. Very impressive.
Alterations is a step up for the band and an obvious positive development of the band´s sound since the Genetic Confusion demo. A 3.5 ( almost a 4 star) rating is warranted.
