Hobbies

Music. Sound Recording. Direction

I love music and I play piano, keyboards, guitar and also sing.  I love both Indian and Western classical, light music and rock/country.  I am a part of a band called 'Surrhyeal'. We have done music for an indie movie 'Kya Yaaron' which was released all over India.

Check out some of my recordings here: https://soundcloud.com/anshumanjdas
Cooking.

I love to cook. It is a great stress buster.

Adventure.
Something that I have begun exploring in the recent times.
 love magic (not that i want to do it). I am keen to know the trick or stunt or the physics behind it. 

 love to watch football. EPL. CL.

 love movies and would like to make one someday...
