Kees Dieffenthaller began performing in the late 90's, fronting a cover band that specialized in Billboard chart-toppers, and popular soca and reggae tracks. Due to his vocal range, stage presence, good looks, and uncanny ability to mimic popular artists, Kees quickly created a buzz and attracted a large, loyal following. On the crest of all this success and momentum, Kees exited the cover band circuit in 2005 and formed his own band, KES, with the dream to pursue great original music. Featuring his brothers Hans (drums), Jon (lead guitar), and best friend Riad Boochoon (bass), Kees was now able to work with similarly focused members on creating original music that could have international appeal.
