Unique for its instrumentation, the Aleph Guitar Quartet (formed in 1993) is a chamber ensemble dedicated to contemporary music. In close collaboration with the guitarists, numerous composers have written works specially for the ensemble, giving rise to a completely new repertoire. In addition to that, the quartet invites these composers to arrange traditional works. In their performances Andrés Hernández Alba, Tillmann Reinbeck, Wolfgang Sehringer and Christian Wernicke emphasise the exclusive character of the ensemble and combine high standards with a sensitive presence. The four musicians regularly perform at new music festivals. Their eponymous CD was produced by SWR Baden-Baden and released on NEOS in 2011.
