With its spec­tac­u­lar con­certs and three released stu­dio albums, the Kalei­do­scope String Quar­tet has estab­lished itself inter­na­tion­al­ly in recent years. The four Swiss musi­cians tran­scend the clas­si­cal string quar­tet for­mat into new dimen­sions, leav­ing behind genre bound­aries and at times elic­it their instru­ments from uncon­ven­tion­al to unex­pect­ed tones. Already on their sec­ond album Curios­i­ty the ensem­ble fas­ci­nat­ed with strik­ing tim­bres and charis­mat­ic orig­i­nal com­po­si­tions. All the more they amaze at sub­se­quent per­for­mances by vir­tu­os­i­ty, dynam­ic joy of impro­vi­sa­tion – and con­sis­tent renounce­ment of any sheet music.

Their third album Reflec­tions includes two com­po­si­tions by Simon Heggen­dorn and one by vio­list David Schnee, but focus­es on pieces by a “for­eign” pen. The ensem­ble com­mis­sioned com­po­si­tions from Nik Bärtsch, Math­ias Rüegg and Nicole Johän­nt­gen, as well as by the vien­nese Georg Brein­schmid, Ephrem Lüchinger and sax­o­phon­ist Nicole Johän­nt­gen.

Rhyth­mic phras­ing and grooves have always been the hall­marks of the Kalei­do­scope String Quar­tet, as well as its styl­is­tic range that extends to folk-like melodies. KSQ was found­ed in 2009 on the occa­sion of a pro­duc­tion in which the strings coop­er­at­ed with a jazz quin­tet. In 2011 the debut album Magen­ta was released, and short­ly after the ensem­ble was award­ed the ZKB Jazz Prize.

The quar­tet per­forms reg­u­lar­ly, local­ly and abroad at pres­ti­gious fes­ti­vals includ­ing the Lucerne Fes­ti­val, Murten Clas­sics, Cul­ly Jazz, Jazz Fes­ti­val Willisau, Lang­nau Jazz Nights, Schleswig Hol­stein Music Fes­ti­val, Cairo Jazz Fes­ti­val as well as in renowned con­cert halls and jazz clubs such as  Elbphil­har­monie Ham­burg, Paul Klee Zen­trum Bern, Moods Jazz Club Zurich, BeJazz Bern and Jazz Dock Prague.

The quar­tet, whose mem­bers are pro­fes­sion­al­ly trained in both clas­si­cal and jazz, have come to define their own musi­cal lan­guage by way of skill­ful­ly elim­i­nat­ing musi­cal bound­aries and con­stant­ly explor­ing the con­nec­tive ties to oth­er music gen­res such as pop and rock. Edgy grooves rise and fall between imag­i­na­tive sound­scapes while folk­loric melodies encounter adven­tur­ous­ly exper­i­men­tal impro­vi­sa­tions.
