“Ensemble d4” – named aner a frequent opening move in chess, which is ideally followed by an extended game – was founded in 1995 to play works that are rarely heard in “normal” concert life. Since 2017, the ensemble of recorder, baroque violin, viola da gamba, harpsichord, theorbo, baroque guitar, and percussion has repeatedly performed concerts with the programma$c $tle “Baroque Disco,” featuring Spanish music in which elements of the later flamenco are clearly to be heard. The fact that the list of names, including Kapsberger, Sanz, Soler, de Murcia, and other contemporaries, results in a veritable “dance fes$val” is due to the truly “fiery orchestral” arrangements developed by the interna$onal ensemble – to be experienced on the now available first “d4 CD.”
