Every now and again music and opportunity line up. Doesn't happen often - live albums are rarely of the best night on the tour, unless the band is recording every night. Often, the tech and the tunes are on different calendars.
However, for Lobelia and I, the planets aligned when we played a house concert in Nebraska a couple of years ago - it wasn't actually in a 'house', it was in a recording studio, doubling up as a venue.
We played the best we'd ever played and got an awesome recording of it.
It's not on bandcamp yet, sadly, but will be soon - til then, here's one of the tracks on last.fm:
