Listen to these beautiful songs of Lata Mangeshkar composed by Laxmikant-Pyarelal..
These songs are woven around santoor and flute...These are played by Pt. Shivkumar Sharma and Pt. Hariprasad Chaurasia, respectively, ...for LP's Orchestra...

Oddly enough, there's not that much santoor and flute in the Aasra song. Lots in the Abhinetri song...

Wonderful songs, though. I think the beat Lata songs have been picturized on Mala Sinha.

It will be interesting to start a thread with discussion of songs with famous instrumentalists/music directors moonlighting from the classical music world.
