SNSD's Taeyeon, Tiffany, and Jessica tease concert album

Even though SNSD has been busy working on their promotions in Japan, some teasers from Taeyeon, Tiffany, and Jessica were recently posted online, grabbing the attention of many. The audio teasers were posted on a Korean website that had no further information on what the teasers were exactly for. It can be assumed that they are for their live concert album. Each teaser lasts around 20 seconds, with Taeyeon singing Hush Hush (The Pussycat Dolls), Tiffany singing Umbrella (Rihanna ft. Jay Z), and Jessica singing Barbie Girl (Aqua). All of them are sung in English, and they sound quite amazing! Check them out below. http://www.youtube.com/watch?v=94dLByeXzBM http://www.youtube.com/watch?v=ao4Jpjpk6t4 http://www.youtube.com/watch?v=PsTwC35101w
