I'm so sorry to hear of Mr. Nussbaum's passing!  I'm so Blessed to have seen him when I moved back home,he was very near an dear to myself an my family.  1974 1975 ? I started taking organ lessons on Albany Ave an followed all way as ateenage an ubove Abraham's  music uptown ? My fondest memory ,was going on the radio  with Bob introducing  a new child's learning of music.  A great loss!

My sincere condolonces on Mr. Nussbaums passing.  He was one of the most influential teachers I ever had from 1987-2000.  I took piano lessons above Abram's music uptown.  My fondest memory was the last end of year recital.  He will be missed.
