Michelangelo Galilei (1575 - 1631) was an Italian composer and lutenist of the late Renaissance. He was the son of music theorist and lutenist Vicenzo Galilei, and the younger brother of astronomer, Galileo Galilei. His music is, in my opinion, some of the most beautiful of the era - the perfect music to play when you cant sleep (hence the bleary eyes!).
The 6-string arrangement of this beautiful music can be found at per-olovkindgren.com/ipnmonitor/index.php?maincat_id=13.
