The recordings were made at the Wiesbaden Marktkirche. The basilica with five towers was built by the architect Carl Boos as 'Nassauer Landesdom' [Cathedral of Nassau] in 1853-62. The main tower of the Marktkirche houses the carillon built by the Dutch bell foundry Koninklijke Eijsbouts in 1986 in a height of ca. 70 metres. The carillon with 49 bronze bells has a weight of 21 tons and is played from a manual lever keyboard. It is only on such a keyboard that dynamically differentiated playing is possible which makes melodies become apparent through different striking techniques and the spectrum of which ranges from powerful sound cascades to a softly fading pianissimo. Built by E. F. Walcker & Cie. in 1863 and later altered and extended several times, the organ consists of 85 stops over four manuals and pedal today.
