Massive stage settings, rock concerts and music as a binding factor, Ajay Devgn-Salman Khan starrer `London Dreams`, which releases Friday, relies on the bond of friendship more than its rock background.
  Produced and directed by Vipul Shah, the movie stars Asin Thottumkal in the female lead, while Akshay Kumar will be seen in a cameo. Rannvijay Singh and Om Puri too feature in the movie.

`London Dreams` is a drama about two friends and their relationships, their roles, individuality and problems," Ajay told reporters.  Added Asin: "It is a musical with a lot of emotions and twists in the story. But it`s something that heavily relies on music."
