There is an article on Arutz 7 about an all-male a-capella group from Yeshiva University who are in Israel for the annual World Bnei Akiva conference. A few months ago I posted a Channukah song by these young men because it was fun to listen to.
Now, I see they have released a CD with many of the traditional songs we all know so well. My favorite is their version of Lecha Dodi, which we sing every Friday to welcome in the Shabbat. Their website is www.maccabeats.com. Do go there and listen to excerpts from the CD (I suggest you buy a copy). Meanwhile, here is a selection of their music...Take time out and Enjoy!
