What's a good piano and guitar duet? And the artist?
Not exactly a duet or a "new age" kind of song but worth mentioning in this thread: 'A Day in the Life' - The Beatles.
rolling stones have some Piano/Guitar blends. That's the only thing that comes to mind.
Yes they made some really good guitar/piano blends. Of the few great pianists that played on their records Nicky Hopkins always been my favorite. I suggest 2 more gems by the Rolling Stones: 'She's a Rainbow' and 'Sympathy for the Devil'.
piano and guitar don't go very well together because the piano is liable to drown out the guitar (unless you're amplifying it). are you thinking more of a piano accompaniment for a guitar tune or equal shares? the former would be easier to find, though i've never actually seen duets consisting of piano and guitar. chamber music incorporating the guitar, yes, but not duets.
It's true, for one, both instruments would fight for their own spotlight. And if the piano is just playing background chords, the piano part can be played by the guitar.
Though you could always arrange songs to make it that way.
Even if we take into consideration the difference between classical piano/guitar duets and pop/rock piano/guitar blends or if you prefer a piano accompaniment for a guitar it would depend if we talk live performances or record productions. For the later it's totally in the hands of the sound engineers and the record producer. They're responsible for making the piano and the guitar(s) electric or acoustic guitar(s) sound well together in the mix like in the aforementioned songs.
