The newly formed Weimar Guitar Quartet playing Uarekena by Brazilian guitarist and composer Sérgio Assad (b.1952). The quartet is made up of Karmen Stendler (who you’ve seen on the site before), Stephanie Jones, Hanna Link, and Jakob Schmidt. This comes via Karmen Stendler’s YouTube channel. Great to see such a talented young group playing together. Not sure about all the players but Karmen (via her bio) is studying at the Hochschule für Musik “Franz Liszt” in Weimar in the class of Thomas Müller-Pering. You can get the sheet music via Amazon: Uarekena by Assad.
