I've been listening to several Neshama Carlebach CDs for a project I'm working on. She has an amazing voice, and the discs I'm listening to are excellent. David Morgan, who produces her and co-writes and co-arranges her work, shows a depth of talent rarely seen in the Jewish market. And Neshama's voice is so polished and shows such a broad range, she could easily cross over to the secular market. A great place to start with her music is Dancing With My Soul. For those who care about such things, check with your rabbi regarding possible issues of kol isha before listening.
