This recording was made hours after I received my Core Sound TetraMic, with no opportunity even to check balance. You hear the end of Vaughan Williams's arrangement of Linden Lea, applause, an announcement, laughter, and the start of Rutter's Birthday Madrigals - sung by the Cherwell Singers in the Holywell Music Room, Oxford (historic, but not actually a particularly good recording venue). (NB - I had not received the shockmount, so it was mounted, as the photo shows, on the shockmount of an AKG C414)
