Question: Are the well-known jazz and classical pianists that the quartet worked with both men? Passage:The Annex String Quartet, also known as The Annex Quartet, is a string quartet founded by violist Yunior Lopez in 2008 in Toronto, Ontario, Canada. Named after The Annex neighbourhood in downtown Toronto, the quartet began performing regularly in Toronto's many bars, coffee shops, and non-classical venues like Aroma Espresso Bar and the St. Lawrence Market. In 2010, they made their American debut alongside the Kronos Quartet at Carnegie Hall, and have since appeared in over 100 performances, recordings, and broadcasts. To date, the group's primary focus has been bridging the gap between classical and world music, which has led them to become one of the most eclectic performing ensembles in North America. They have performed, recorded, and ventured into various musical styles, and continue to work with a diverse range of artists including classical pianist, Jan Lisiecki, Cuban jazz pianist, Hilario Duran, and Canadian jazz icon, Jane Bunnett. Following multiple recording collaborations with a diverse range of artists, The Annex Quartet released their official debut album, The Roaring Twenties, in June 2013. The quartet's current work in progress is an all-Cuban album featuring famed Cuban Bolero singer, Anais Abreu. They are currently the ensemble-in-residence at Midtown Music School in Toronto and The Stratford Summer Music Festival in Stratford, Ontario.
