I have great news about B. Michael Williams, as well as some sad news. On the plus side, he is making a strong finish to his career as an academic, a percussionist, and a proponent of the mbira and karimba: he has just published his 5th and final volume of mbira songs in his easy-to-read mbira tablature, available from Bachovich Music Publications or Steve Weiss Music.
On the sad side, Michael tells me that he has been diagnosed with both Parkinson's and Alzheimer's diseases. While he had the wherewithal to assemble his final volume of mbira songs, currently he is no longer able to play mbira.
Michael is a great teacher, and helped a lot of people to learn and play traditional mbira and karimba. And even though a lot of my work is non-traditional, he has always given it validity, and his encouragement has meant a lot to me.
So, when you pick up your mbira, your karimba, or your kalimba, please send some of your joy and good vibrations and gratitude to our dear friend B. Michael Williams. Thank you.
