Psychedelic rock, folk-rock, progressive rock. The six members of Cuprum quite openly confess to their strong affection for the good old big beat. Drums, bass, acoustic guitar, electric guitar, Hammond organ and flute with two singers performing songs with Czech lyrics. Once an attempt at a pure progressive rock, the project has gradually spread its wings across multiple sub-genres, which will surely be appreciated by all fans of Jethro Tull and Ariel Pink.
