Not just poetry - but anything well written/ researched/ expressed. I am a massive bookworm and will read anything from history to poetry to novels and lots else in between.
This. But yeah, I read, among other things, a lot of poetry. I started out some years ago, only to see if it could get me to become a better lyricist and songwriter. It was tough in the beginning, I could hardly muster getting through a single poem. Today, it has a life of its own outside my musical ambitions. I read it because I love it. That doesn't mean I love every poem nor poet, It's just like music, painting or whatever art you like, it's best when you in some way can relate to it.
Right off the top of my head;
Thomas Hardy
Ben Jonson
Charles Bukowski
Arthur Rimbaud
Emelie Dickinson
Robert Burns
E.E Cummings
John Keats
William Blake
This to name a few. There's a million other really great literary giants out there. But like Tone say, it's all a matter of taste.
Surf the net like a madman and you will find who you like eventually. That's exactly what I did and it even got to the point that my wife one day told me "This night-surfin' the net for p...oets has got to stop!"
We all got domestic issues in various degrees I'm sure, but I might be the odd one out on this particular one!
Cheers,
Peter
