The XL Tuba Quartet was the first chamber ensemble of this kind to be established in the region. The quartet was formed in 2002 by Krunoslav Babić who still plays with the ensemble, together with Aleksandar Benčić, Viktor Kirčenkov and Jurica Rukljić. The quartet members are also professionally engaged in soloist positions of leading Croatian orchestras. The quartet’s objective is to present the tuba not only as an orchestral, but as a soloist instrument as well. They perform a repertoire that covers old masters (Palestrina, Bach, Händel...), classical and romantic periods, as well as jazz and works written by contemporary composers that include numerous Croatian artists who have dedicated their works to the quartet. Apart from works written originally for tuba quartet, they also perform standard baroque and classical pieces arranged by leading wind instrumentalists of the latter 20th century. The ensemble has given numerous concerts in the country and abroad (in Germany, Italy, Slovenia, the US, Malaysia, Thailand, Australia, etc.). They have so far released three records.
