beginning of 1985, asif iqbal could not continue as the drummer due to family reasons and introduced mahbubur rashid as his replacement to the band. in addition, by this time the band decided to pursue heavy metal music and have done away with the keyboard section. at this point the band consisted of mainul islam on the guitar, imran hussain on the bass, asif alam on the vocals, and mahbubur rashid on the drums. while studying for their secondary school certificate examination mahbubur rashid came across the name rock strata in the geography textbook assigned for the exam. the name stuck and was gladly embraced by all the other members of the band; hence rockstrata was born. the first ever logo of rockstrata was created by shahriar hussain who is a cousin of imran hussain. the logo was first drawn on imran's guitar case. during 1985, while members were enrolled in notre dame college the jamming sessions went on, although not on a very regular basis. during this time, one fine morning, while on their breaks in between classes at the college canteen, mainul was talking to someone about the newly formed band and mentioned "i will only be interested to do a band like black sabbath" which was overheard by arshad amin who was also having a break at the canteen. considering that not many people talked about black sabbath at the time, arshad went over to mainul to further inquire about what's going on and a lifelong relationship begins. mainul then introduced arshad to imran, mahbub, and asif later. at the time the band members were increasingly becoming fans of iron maiden and planned to mould rock strata in the same die, with two guitars. at this point imran switched from bass to guitars and arshad joined rockstrata on the bass. this works out nicely for all since arshad was a big fan of pink floyd and roger waters, in particular. this completed the band and the first ever line up of rockstrata was asif alam on vocals, imran hussain and mainul islam on guitars, arshad amin on bass and mahbubur rashid on drums.
