i've never thought music was about technical skill, but more the feeling you can convey thru it, if you can convey your feeling thru 3 chords and no solo then thats fine.
i have always been a nirvana fan, as well as a fan of a lot more technical playing styles. to me its about the music, if i'm writing a piece of music and i feel a solo will enhance it, then i try it, if i feel it does not need on i dont force it.
i'm a pretty gheto guitar player, and just as ghetto a song writer, but i do my best. but i never feel i need to force a solo into something
