"Stop it! lower the volume! how can you listen to this!!!" are the kind of responses one would expect from parents to their kid listening to rock music (most definitely in the Indian context!). Can't really blame the parents who have grown up on a music diet of M.Rafi, Lata, Asha and Kishore Kumar. I'm sure they would've faced a similar predicament when a 'roop tera mastana' or a 'yeh mera dil' was being aired on the most eagerly awaited 'Binaca top 20' radio show. So the whole "rock is loud, noisy and evil" notion might just be one of the many manifestations of the generation gap.
Rock music was a musical style that arose in the US in the mid-1950s. Its basic elements consist of one or more vocalists, heavily amplified guitars (rhythm, base and lead) and drums. Its roots lay in rhythm and blues (R&B) and country music. The 60s saw the emergence of Beatles and Rolling Stones as also the blending of folk music with rock by Bob Dylan. the 70s saw the rise of writers/ singers like Paul Simon, Neil Young and rock assimilated other forms of music to produce jazz rock, heavy metal and punk rock. The psychedelic rock band Pink Floyd (known for its elaborate live shows) experienced great fame and commercial success during this time with albums like Dark Side Of The Moon (1973), Wish You Were Here (1975), and The Wall (1979). The 80s experienced the disco influence of artists like Madonna and Prince while by the 90s rock had incorporated grunge, rap, techno and other forms.
Contemporary rock has been criticized for the values it portrays. However to date no valid evidence has been produced to link even the more objectional form of heavy metal music as an agent to specific patterns of anti-social behavior. So rock on!!
