So me (guitarist) and my friend (pianist) are planning on starting a duet. We are not gigging yet, but we need some nice songs to play. Any style will be fine, we just need songs to practice.
If you like Joey Cape you could check out "Making Friends" and "Twenty-Seven"
The Cure - Out of this world- from the album Bloodflowers. Great piano part.
"Pain or damage don't end the world nor despair, nor fuckin' beatings. The world ends when you're dead, until then you have more punishment in store. Stand it like a man, and give some back."
I imagine you have heard of the band Dream Theater. The guitarist (John Petrucci) and keyboardist (Jordan Rudess) did a live, (mostly) acoustic album together called An Evening With John Petrucci and Jordan Rudess. As you can probably imagine, most of the songs are rather difficult to play. Regardless of your skill level, I highly recommend listening to this to either get some great songs to play or setting some high goals for yourself.
Here's one of the tracks:
