When you put a trained musician behind his/her instrument, the artists’ age, background or anything that constructs their journey, just stops mattering for the duration of the performance and the stage is theirs to shine on. That is the ideology with which Responsible Charity, a non-profit created by Hemley Gonzalez in Kolkata, works and now, it is coming up with its first-ever SlumJam concert in Pune at the Chef’s Way Cafe.
