There was an unusual conjunction of various gharanas of Indian Classical Music in Pandit Abhisheki Ji as it was evolved after deep thinking.

Under his tutelage in a gurukul-like setting, Mahesh was extensively trained in classical and semi-classical forms like thumri, dadra, tappa, bhajans, and marathi natya sangeet for over 8 years.

Mahesh is married to Purva Gujar-Kale (m. 2005) and they run non-profit Indian Classical Music and Arts Foundation together in San Francisco Bay Area.

Mahesh has performed in hundreds of concerts of Indian Classical and Semi-Classical Vocal in India, US, UAE, UK, Australia, Europe, and Southeast Asia.

Mahesh has also performed at non-traditional avenues like the NH7 Weekender,[2] Pune (2018), 26/11 Stories of Strength[3] tribute concert at the Gateway of India (2018, 2019).
