While I’m vacationing in sunny Southern California this week, I thought I’d leave you all with a few ensemble videos I like: a duo on Monday, a trio on Tuesday, and a quartet on Wednesday. All this is a lead-up to the next issue of Classical Guitar, out in November, which contains a Special Focus section on “Duos, Trios, and Quartets.”

We’re staying modern with Sérgio Assad’s Uarekena, a wonderful and complex piece, played here with marvelous precision and feeling by the young, quite fantastic Germany-based (but truly international) Weimar Guitar Quartet—Karmen Štendler, Stephanie Jones (both of whom we have featured previously as solo players; click on their names to watch), Hanna Link, and Jakob Schmidt.   —Blair Jackson
