Progressive Rock,a much maligned musical genre,often categorised as long-haired blokes showing off,which is only partly true.
But at it`s best it can take you to places most music can`t,at it`s worst it`s over-indulgent twaddle.
Anyway here`s 3 of my favourites,what`s yours ?

Genesis-Stagnation.
Any Peter Gabriel era album is class,so hard to pick one but this near 9 minute classic is one of the best,from the last album not to feature Phil Collins
All the best elements of Prog here,amazing playing from all the band,many different styles in one song and not a clue what it`s about !
All from a bunch of 22 year olds.

Pink Floyd-Shine On You Crazy Diamond Parts 1-5.
How do you pick one Floyd song ?
I`m not a huge fan of the Syd Barrett era,so apart from that and probably the last album,you cant go wrong really.
Simply the greatest Rock band of all time.

Steven Wilson-Ancestral.
Steven who ? .Sometimes called the biggest rock star in the world that no-one has heard of,but put simply the bloke is a genius.
He`s been making music since the late 80`s in bands such as Porcupine Tree(Also great),and has released 6 solo albums.
This track comes from his 2015 album Hand Cannot Erase,it`s nearly 14 minutes long and changes style about 5 times,from Pop to Heavy Metal,and most things inbetween,top stuff.
