When I told them how much I enjoyed the set they played at our showcase, they informed me that they weren't really a hundred percent; they had been gearing songs down into lower keys because their voices were hoarse, and they were both nearly exhausted from the grueling perfomance schedule they'd set for themselves.
"We owe you a show," Cara told me, explaining that even though I thought they sounded great, they were usually much better.
I suggested that they play an "office concert" for us; that is, stop by our office some time and play a few songs for our crew on our lunch break. Considering that they don't even live in the same country as us (they're Canadians), I didn't really expect them to take me up on it, but that's exactly what they did.
