NMK I don't know if you are aware that all these bands, musicians were eradicated in ~2004 by the MMA government?
When I was a kid (somewhere around 1980-82), while passing by Dabgari bazzar (with my father on his vespa scooter) I used to count the number of drums (dhoolki) hanging in the balconies of those Bala Khanas. I used to feel very happy whenever I out-numbered my previous day counting.
