The Seattle Chamber Music Society summer season is real--well, "virtually real," with 12 new performances! And it's a bargain too. If you sign up before July 1, it's $100 to subscribe to all 12 concerts, (or $15 per concert, separately). Multiple people could listen together in the same room on one purchased link.
(NOTE: The season price goes up to $125 beginning July 1.)
