Bach.

Some years ago, the 8th CD was released, entitled ‘The John McLaughlin Suites’. This CD contains arrangements of compositions by the English jazz guitarist John McLaughlin. In October 2004 the duo released the new CD ‘Dedicatoria (homage to Julian Bream)’. This CD contains works by Enrique Granados, Isaac Albéniz and Robert Schumann. Master guitarist Julian Bream wrote about this CD: ‘This album sounds very well! Thank you for the dedication.’ In March 2005, the professional magazine ‘Luister’ awarded the CD with nine points out of ten.
In April 2007 the new CD ‘The Crimson King Fantasy’ was released, with arrangements of music by the British rock band King Crimson. Guitarist Robert Fripp (the founder of King Crimson) wrote about the arrangements: ‘My congratulations on your work. Superb.’
A new CD will be released soon. This CD contains the complete works for two guitars by the Dutch composer Jacob ter Veldhuis. Almost all works on this CD are dedicated to the Groningen Guitar Duo.
