This is a great CD/ DVD combination. Incidentally, I think that you'll have to order this "Digi Pack" version to get the DVD. The CD is a mixture of songs off KT's "Eye to the Telescope" and other songs from her back catalogue, but recorded in live unplugged session style. The DVD includes a making off documentary, which gives background to why the recording sounds so fresh - they basically set up and rehersed one day, and recorded the whole album the next. All is someone's front room. This gives versions of songs that are much better than on "Eye to the T", which always felt a bit forced and over-cooked to me.
Interesting historical note - "Acousic Extravaganza" was the name that KT gave to the music nights she used to run in Edinburgh, when she was on her way up. And this recording is a return to a more natural, intimate style. And it lets her real tallent with a softer guitar playing style and voice come through.
One final note - the "parental advisory" only applies (as far as I can tell) to the first track, where one should indeed be advised. From track two on this is my five year old son's favourite bedtime music of the moment.
