Reading Erik Levi’s article on Glinka (November), I will confess to not knowing as much of his music as I should. However, I do possess a wonderful live recording of his Sextet in E flat, for piano, string quartet and double bass, part of a set recorded at the Lugano Festival in 2009. For anyone who enjoys chamber music with unusual instrumental forces, I would recommend it. All six players, led by pianist Polina Leschenko, are clearly having great fun. I would be interested to hear if any other readers have views on other recommended works by him? Ian Morgan, Malvern The editor replies: The recordings made each year at the Lugano Festival have, in general, been a wonderful treasure trove for those wanting to investigate rarely performed repertoire. Sadly now discontinued, this brilliantly programmed and performed summer event will be badly missed.
