A brief commercial post here.
Through 1.6.19, I am selling my 4-CD set “300 Gems of Irish Music for All Instruments” for $4.99 USD, a discount of 75%. See https://greylarsen.com/webstore/holiday-cd-book-sale/ for details. The 300 tunes are available for MP3 download as well, for $9.99. This costs less than getting the CDs if you are in Canada, Mexico or outside of North America.
Also, 10% off on Carbony whistles, Folk Flutes by Casey Burns. $7 off my Irish music books, $7.99 or less for most CDs.
Thank you for your time!
