I've been playing this disc a lot, both in the car and at home, and it's a total winner. Very discrete and the music is excellent. This album contains 7 acoustic tracks and 5 electric tracks. The style of music is probably considered "Folk Rock" to some, a little country maybe, and a bit pop-rock. It's very harmony intensive, both from the singers voices and their guitars. Each of the singers in heard from their own front speakers, and their guitars are heard in the backs. It gives the listener a very clear and concise soundstage. The songs are excellent, all penned by the artists, and you will find yourself going back to them over and over. (At least I did)
Dietrich and his crew are doing a fine job with their "quadraphonic" series of DVD-A releases, and this one has the potential to be their most popular title, world wide. These artists are from the US, and the vocals are all in English, so just because the disc is from Germany don't think their vocals are in German.
Each artist has their own website, and they also have a joint website. The CD version of this album, which was released in 2011, is available at many places in the US, but the DVD-A is only available directly from QuadroSurround. If you like CSN/S&G "like" harmonies and guitar driven folk/rock, I believe you will really like this album. Support Dietrich and check this disc out. You will be glad you did.
