2) The Michael Schenker Group (or shortly MSG) is a guitar-oriented hard rock band formed in 1979 by the former Scorpions and UFO guitarist Michael Schenker, brother of Scorpions' guitarist Rudolf Schenker. From 1986-1992, the band was known as the McAuley Schenker Group, due to Schenker wanting to split the writing process in half with vocalist Robin McAuley.

The music is best described as mostly melodic hard rock with progressive undertones. Schenker is famous for his half-black, half-white Gibson Flying V and for his unorthodox approach to lead guitar. He is sponsored by Dean Guitars and is well known in the neo-classical genre. Read more on Last.fm.
