Spanish instrumental project KOTEBEL aims at developing elaborate music with complex harmonic, as well as quite pleasant melodic and rhythmic structures. These elements are created by using resources which come from the worlds of Progressive rock and classical music. As the title of its first album "Structures" implies, the group lays down its framework for future masterpieces. Seven independent pieces explore different styles within the Progressive rock genre, based on the extensive use of keyboards and flute. It can be placed amongst PREMIATA FORNERIA MARCONI, Tony BANKS, THE ENID or early GENESIS. "Mysticae Visiones" (2001) is a concept album based on the musical representation of a series of metaphysical concepts, including birth and death. The first eponymous piece (35 minutes) is a suite that integrates different Progressive rock styles with elements from classical music (Impressionist period) and other genres. The second piece, "The River" (15 minutes), based on a fragment from the novel "Siddhartha" (Hermann HESSE), blends oriental resources with symphonic rock. With its female vocals, its jazz-rock parts and its flute ala Airto MOREIRA, many sequences of this opus could have been played by Chick COREA in the Seventies.
