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.
