Invocation is the 2002 debut album by the Canadian technical death metal band Sympathy. The album was published by Fear Dark, a Dutch record label.
Although suffering from low production values, the album got positive feedback in underground metal circles and magazines such as BW & BK and was mentioned in Metal Maniacs magazine as one of the reader's albums of the year for 2002. Noted for solid songwriting, Sympathy has since re-recorded several of the album's songs with better production.
The music features deep growling, occasional shrieking, heavily-distorted guitar sound, plenty of tempo-changes and atonal riffs, some symphonic keyboards and computer drums. "Prelude and Toccata in e Minor" is a piano instrumental, and "Christus Factus Est" features operatic female vocals. The album cover was done by Jeffray Arwadi of Soundmind Graphics, also known as the guitarist/vocalist for the Indonesian avant-garde metal band Kekal.
