Nirvana and Hendrix are both good for beginners. You'll learn basic chord structures as well as some lead to coincide with the chords.
For Nirvana start with Come as you are, then Teen Spirit then advance to On a Plain or Lithium.
For Hendrix, start with Hey Joe, then Fire, then Foxy lady....then advance to Little wing, probably Hendrix most complicated song.
After you've mastered these bands throw yourself in the deep end and learn the likes of Metallica, Van Halen, Gunners.......then it's welcome to hair heaven, the best of the best guitarist wise!
