was written and composed at Salman Ahmad's residence where the band had been lodged. Shoaib did all the lyrics while Junaid and Rohail composed the songs. Continued success (1989–1992) With the release of their first major single, Vital Signs began to achieve recognition in Pakistan. Their debut album, Vital Signs 1, was a success leading a wave of fresh new acts in the country. Most of the new acts were part of the many "youth festivals" that began to do the rounds in Karachi and Lahore, especially after one such show was specially conducted and televised by PTV in late 1989. Shoaib Mansoor also directed a mini-drama, Dhundle Raste, about the true story of the band, in which the band members acted as themselves. The band soon went on a tour throughout the country, playing sell-out concerts in Karachi, Lahore, Islamabad and Peshawar.

The tour also changed the way the band looked, and the band saw the emergence of grunge and a revival of interest in '70s music, and became instigators of fashion. The change also saw Rohail, Shahzad and Junaid moving to Karachi (Rizwan decided to stay back in Islamabad), as Rohail started constructing a brand new studio in his Karachi apartment. After performing a number of concerts managed by Rohail's elder brother Zahid, the group headed out
