Ed Lippmann joins us at 10:40 am for Part 3 of Technology and Architecture and this week Ed moves on to the Gothic and Medieval period and concludes with the Renaissance.

At 11:00 am, my special guest is Saul Smith of Soul Drummer talking about the djembe. This versatile African drum has an amazing history and capability and Saul brings it to life.

Music is mostly drumming, with a little bit of Africa thrown in.

I look forward to your company.
