I didn't grow up in a very musical house -- if something was on, it was almost always NPR. Luckily for me, Peter did grow up in a musical household, and listening to something fun at dinner is one of the best things he has introduced to me.
The only offerings I brought to the [dinner] table were Tony Bennett's "Unplugged" and the complete Michael Buble collection. Awesome (obviously!), but not exactly extensive. Here are some new favorites, all excellent dinner companions:
She & Him
Forro in the Dark
Super XX Man
John Pizzarelli Trio
