Mahvash began her music career in early 2007 when she decided to be a part of the newly formed Laal Band along with Haider Rehman, Aamir, Asif, Salman and Jamal.
Laal the Band was formed in late 2007, after the sacking of the Chief Justice Iftikhar Chaudhry.
The band members along with the public protested against the incident and demanded the restoration of judiciary by the president.
The band's aim is to popularize the works of these socialist writers by setting their revolutionary poetry to music.
Mahvash has played backup vocals for Laal band's debut album, Umeed e Sahar.
