Italo post-disco group formed around the nucleus of Mario Boncaldo [Italy] and Electro-Soul-House master Tony Carrasco [USA].
The principle vocals were performed around American Italian jazz singer Rossana Casale and American chorus singer Naimy Hackett. The electro catchy techy disco sounds and melodies were all produced, written, arranged, and mixed by Mario Boncaldo and Tony Carrasco, and co-arranged with Davide Piatto.
Tony Carrasco produced and mixed the last recorded Klein & MBO release in 1986, entitled Keep in Touch, while his former partner Mario Boncaldo decided to go solo and formed the italo dance group MBO.
