A double-LP set deserves a long title, and this one has one! This is Shell's Wonderful World of Music: Special Christmas Edition by the Longines Symphonette Society. According to Wikipedia, The Longines Symphonette Society was a record label created by the watch company Longines. Makes perfect sense.
Here are 20 carols performed in the wholly inoffensive choral/orchestral tradition ("Little Drummer Boy", "White Christmas" are highlights), with arrangements that are clean and straightforward. This is great background listening for Christmas gatherings where you don't want bombastic, jazzy or swinging variations to overload your celebratory subconcious.
It's difficult to believe in this day and age that gems like this were sold on the cheap in Shell gas stations all over North America! I believe this set was once issued on CD, but it appears to be long out-of-print. Don't let it remain neglected! Download and simmer down with this pleasant Christmas musical trip.
