Inge, My solitary guess is Nina Stemme, but I am truly not musically inclined... However, I really DO like that metallurgical scope with encoders on the stage!!

I have uploaded a 3 minutes long song under the folder 'Reports for Technet/NTC'. My favorite singer. When she does this one the hair rise all over my body. Can you guess who she is? The one who is correct will get a copy of the most deep diving Tin whisker report I have seen. I've got permission for one and only one copy, more than 100 pages, not known within the USA . And he/she who wins has no right to copy to others. Just ONE guess!
