We have the CD that the Voices of Liberty in EPCOT recorded. The artist is listed as “Liberty Voices” and it says “We the people” on the cover w/ the flag and statue of liberty.
I was speaking to one of the singers last week after their set and he said they had a new album for sale on iTunes and the CD would be in the gift shop later this year.
I’m having trouble finding it. (If I recall they may have a christmas album too.)
Any help would be appreciated.
I found this link: http://www.libertyvoices.com/musicCDs.htm
The Acapella Americana cover is different but it lists the same songs as the album I downloaded from iTunes which has the same cover as the one you described.
Thank you so much. I found the new one:

They are recording under “the voices” now. I wish they just had albums by “the voices of liberty” and it would be even easier if Disney actually produced the albums! 
I just listened to some of the previews. What an amazing sounding album. I will be adding it to my collection.
thanks for sharing, DH loves VOL this would be a great stocking stuffer this year.
