One of the earliest champions of neo-classical metal, Uli Jon Roth got his start with the Scorpions in the 1970s and continued down a solo career that saw his focus shift more to classical composition as his guitar sensibilities expanded to new realms. In the mid-‘80s, he introduced the Sky Guitar, an instrument which spans six octaves. Since 2006, he’s been teaching ambitious music-making seminars that he calls Sky Academy. Roth will be performing at Stage 48 on Feb. 6. He will also be hosting a Sky Academy on that same date.
