|Pianist Hal Galper|
Galper has written some very informative books. One which I enjoyed is called "Jazz Piano Voicings". It's a lot of written out voicings, but also some good philosophy. Here are some pearls of wisdom from Galper:
"....I have always considered the piano to be a superfluous instrument in a jazz group. It is just not needed. The other instruments are already fulfilling the melodic, harmonic, and rhythmic roles. Because of it's ability to be so interruptive, the pianist's role in a group is then very sensitive, and must be used with restraint...."
The gig is from 4:30 to 7:30 PM. I urge you not to miss it! I leave you with a clip from youtube:
