Can there ever be anything more beautiful than this! I am so grateful that someone taped this from the television. For a recording with less distortion (the resonances that these men make are so great that the confound normal television microphones--especially Georgian ones from the 1960s or 1970s) I would suggest getting this disc and listening through great speakers or headphones. The whole recording is remarkable, but there is something special about this particular piece (and I prefer the ending on the recording). You can also listen to it on Last Fm, but I can't seem to get it to play more than the preview.
Here is Cincaro, another piece that Gonashvili and the Rustavi Choir sing on the above-mentioned Georgian Voices CD, that is recorded in higher fidelity.
