We didn't know if this band would be very good - not having seen them before - but they certainly were. A few songs in, one particular song seemed familiar, and very good, but I couldn't recall who the original artist was. A friend pointed out it was 'Rolling in the Deep' by Adele. I listened to Adele's original this morning and don't like it as much as this cover band's take last night. The one thing I would say would lift this band up to the level of the very best, would be the addition of a keyboard player.
