Liquid Monster is the sixth album by the German metal band Brainstorm, released in 2005. The limited edition digipak and the Japanese edition contain a DVD with the documentary Streets, Stages & Studios and bonus tracks.
Norway's Scream Magazine gave a 5 out of 6 score, calling it a "fine power metal album" and a bit more varied than their previous two to three releases. Rock Hard gave a similar score, 8.5 out of 10. Liquid Monster was both powerful and catchy enough to distance its competitors. Metal.de rated the album even higher, at 9 out of 10. Liquid Monster contained "the best power metal you can get in Germany and far, far beyond". After a few listens, it became clear that the songwriting was "even more compelling, mature, and sophisticated" than before.
' published two reviews of the same album. They agreed that the album was excellent. The band "managed to exceed the undoubtedly very high expectations"; "I can't for the life of me find a single weak point".
All songs written and arranged by Brainstorm.
