Writing a contrast paragraph: Johnny Rotten vs Rostropovich

Johnny Rotten and Rostropovich are like water and oil, so different. The first one is a punk singer, but in contrast, Rostropovich plays an instrument, chelo, classical music; Johnny Rotten always wears spiky and dyed hair and scruffy clothes, while Rostropovich doesn't join any fashion. Furthermore, their origins are different too, because J. Rotten is from the UK, though Rostropovich is Russian. The audience that assists to their concerts have also differences, because Johnny Rotten's audience is young than Rostropovich's, that tends to be older than the others. Besides, Rotten and his band play both in opened stages and closed locals; however, Rostropovich only plays his music in chambers and opera theatres. Finally, their music topics are opposite, because Rotten and the Sex Pistols' lyrics talks about anarchy and freedom. In contrast, Rostropovich only plays instrumental songs about nature and drama. To sum up, Rotten and Rostropovich aren't in the same wave.
