While still studying, Sanjay recorded 3 albums with his first band Shristi, which brought 'fusion' music to the mainstream audience in Nepal. Sanjay toured America twice with Shristi before joining 1974AD in 1999. With 1974AD Sanjay has recorded 3 albums and toured America, United Kingdom, Asia, India, Qatar, Australia, Germany and Belgium. In addition to his busy touring schedule Sanjay has performed and recorded with many high profile national and international musicians including, renowned Buddhist nun and vocalist Ani Choyang Dolma, bamboo flutist Manose Singh, Grammy award winning bluegrass singer Peter Rowan, British folk singer Donovan Leech, Max Lolo from West Africa, Jesse Van Ruller from the Netherlands, Sunny Jain Collective, New York and Richard Hardy, the saxophone player for Carol King and the Dave Matthews Band and Sachal Vasandani, Jazz Vocalist from New York.

While Sanjay's first instrument was the Nepali folk instrument/hand drum the maadal, his experience has led him to experiment with fusion, rock, classical and now jazz in various side projects including The McTwisters (led by Berkley trained Czech saxophonist Peter Kroutil), Stupa (with band member Nirakar who play regularly at Moksh) and Project Experience (with Robin Tamang, Nirakar, Kutumba and various other renowned musicians).
