Double bass player Koos Wiltenburg (1954) has a long and distinguished record and has played with jazz greats like Lee Konitz, Slide Hampton, Charles McPherson and Benny Bailey. In the seventies and eighties, Eef Albers was one of the most in-demand guitarists in the Netherlands. For a short time he replaced Jan Akkerman in the super group Focus. Later, he worked abroad with leading musicians including Gerry Brown, Bob Malach and Stanley Clarke. A few years ago, Wiltenburg formed a quintet with his closest musician friends. Apart from Aalbers they are: Leo Janssen on sax and clarinet, Arno van Nieuwenhuize on drums and Thomas Zoetelief on guitar. The group's debut album was released in 2008 with the humorous title What a Wonderful Day for the Blues. This album of the band's own compositions offers room for authentic funk and blues with howling guitars, as well as tranquil, almost spiritual moments.
