Despite being a member of one of the biggest progressive metal acts on the scene today, the music you'll find from Mariusz Duda's Lunatic Soul is just about as far away as you can get from anything related to metal. Lunatic Soul clearly is a project with different intentions than that of Riverside, with its reflective and emotionally compelling style of new age often leaning more towards dark ambient than anything rock-oriented. Though the wordless, atmospheric, and experimental nature of Impressions may not be a guaranteed success for all fans of Riverside, it's clear to me that Mariusz Duda struck gold with this spectacular effort. Those who enjoyed the first two Lunatic Soul albums should find no difficulty falling in love with Impressions.
