I just got back from Aloha Camp where I discovered Mark Nelson's new awesome CD, UKE-A-RAMA. I have to plug this as a wonderful example of the versatility of the ukulele and the eclectic tastes of Mr. Nelson. Try the samples at Mark's site: http://www.mark-o.com/. Remember "that which is not slack key (and does'nt kill ya), makes you stronger". This CD is a blast!
