Interesting Areas in Harlem

I often times walk around in Harlem to explore the area and I have found the area East of St. Nicholas Ave is much more lively than the area near CCNY. Two places in particular I enjoy are Adam Clayton Powell Square (Adam Clayton (7th) and 125th) and Paris Blue (Adam Clayton and 121).
In the square I have found once to twice a week there are usually out door African drum performances, and I am sure they will taper down as it gets colder.
At Paris Blue there are free live jazz/blues shows starting from 830-9pm nightly.
