NPR's Live in Concert from All Songs Considered podcast recently featured 74-year-old Canadian poet and songwriter Leonard Cohen, who is currently on his first U.S. tour in more than 15 years. It's beautiful and provocative ... Cohen's (now) bass voice is richly set in the lush texture of a great backing band and he works his way through a variety of well-known songs from his vast catalog. His lyrics cover a gamut of topics--spirituality to sexuality, politics to music--and are always engaging, often catching the listener off-guard with their playfulness and wit.

You should really give it a listen.
