Sinatra's Jolly X-mas on MoFi is pretty good. BUT, the old time best for me, and also my standard test CD for male vocals, is a CD of traditional X-mas music sung in Enlgish by an Italian group called Neri Per Caso. The group is composed of three brothers and their two cousins, all men in their mid twenties from Naples (a city with a great vocal tradition). They are actually a successful pop group in Italy, with at least one # 1 hit a few years back (Le Ragazze). The thing is, most of their songs are sung entirely a cappella, they do amazing 5 part harmony, and they have a wizard for a recording engineer. Their version of "God Rest Ye.." will raise goosebumps on your arm..and my Guarneri's LOVE these guys (must be an Italian thing). On some songs from their most recent CD's,the soundstage is truly wrap-around. Not sure where you'd get it in the US..but this disc is THAT good. Wish I could let you all borrow my copy....
