Remember The Singing Dogs? It was a band made up of dogs, and all the songs were spliced-together dog barks. The group's Christmas song, "Jingle Bells," hit the top of Billboard's Christmas Singles chart in 1972. But don't be fooled—The Singing Dogs' Christmas album is far from the quirkiest piece of holiday music out there. Stacker dug into the recesses of Christmas or holiday-themed albums to find 15 unconventional holiday albums that stand out as cultural and musical anomalies in their addition to the much-beloved sub-genre of music. These original albums represent some of the most unique holiday songs out there. To curate this list, Stacker didn't look at singles; just LPs and EPs were considered. Many famous musicians have released some pretty unique versions of holiday songs. Sufjan Stevens took it to another level and released 100 songs in two installments six years apart. Afroman has a quirky Christmas album with lyrics tailored to his image and some of his favorite pastimes. Even Arcade Fire put together a secret DIY Christmas album.
