If there has ever been 2 things that have gone together nicely, it has to be a tall glass of melonade and your favourite local jazz bar. The melonade reference is actually kind of a private joke relating to HomeStar Runner (do a google for it) but you get the point - The Piano Bar, Is Where it's At!!
But of course there are piano bars and there are piano bars, if you know what I mean. For instance there is a cafe in Rochdale town centre indoor shopping centre which has a nice little Yamaha grand in the corner that gets played by a nice man who goes through nice melodies for the nice customers. It's a very NICE piano bar - and there is nothing wrong with that of course.
And then there is somewhere like Matt & Phred's in Manchester. Now THAT is a real piano bar. Strictly speaking it is more of a Jazz Bar because the music is rarely a solo pianist but is a traditional Jazz trio setup with no vocalist. Different bands come to play this very popular venue where you can order freshly made pizza and other such goodies. I once puked all night long after eating a pizza from this place but I have no evidence that the pizza was to blame so I shall refrain from claming as much :)
So yes, I hope you now feel the urge to go and find your local piano bar. Enjoy a melonade on me!!!
