The story of every other rock band out there... and not just here in India and Pakistan. Some of the sacrifices that musicians make for their passion are highlighted here. Having a family that doesn't support you... lack of finances... record label's atrocities... things that suck the creativity out of an artist's heart... they're all too common...
Shankar-Ehsan-Loy are big names in the Indian music industry. They're what you might call 'Commercial' musicians. But if you listen closely, their music shows influences of standard blues and rock music (a studio named after Hendrix's famous track 'Purple Haze' should also be a hint ;] ). And the sound production (quality and clearity of the over all recorded music) is ten years ahead of any Pakistani musician, well... the studio equipment that they're working with has more to do with that, but none-the-less, it's good. Also, I especially love the bass grooves that they worked out. Its ironic that an instrument that often gets overlooked in our music scene is one of their strong suites (Indian cinema as a whole), since bass is responsible for filling up the gaps and bringing out the feel.
The music they produced for the featured band named Magic was more pop-ish rather than what you'd expect, especially with the actual underground scene in India bursting out these days (with Farhan Akhter's melow vocals, although he didn't fail to impress in the final concert with the song 'Tum Ho' :

But I think it's somewhat of a forgive-able sin, since some of these underground acts were tactfully placed throughout the movie and the background music in the movie was also great. I guess educating an audience in music couldn't be done overnight and this seems to be a good effort in feeding them in small chunks.
There were a few forced instances in terms of direction though, just to make it all come down to the main story board. But overall I'd say it's a good watch, and would help bring out the underground rock musicians to a mainstream market.
