Martin Klett has referred to his new project "Lamento" as both an "insane project," and a "matter of the heart." He writes: "Insanity and the heart fortunately go very well together. The project of doing Bach concertos with a chamber ensemble of solo strings had been going around in my head for almost a decade. And Bach, in a way, is the core of the programme on this album. His music often tends to be combined with other works: with new music, or with Romantic music. Piazzolla's Four Seasons are often coupled with those of Vivaldi. Thus the idea of combining Baroque music with tango isn't new. But this specific repertoire is something quite different. Then we have my personal journey with tango: my ensemble Cuarteto SolTango and my passion for dance. What grew out of all of this? a rather large-scale project with musicians from many different countries- and an intense week I will probably never forget."
