I feel you may be misguided in what you are posting.
are you referring to what bands have tried to make a difference in the world, or what bands have contributed to the greatest music i history?
According to VH1.. greatest Heavy rock bands,…
Led Zeppelin is number ONE.. And Black Sabbath is Number 2, and Jimi Hendrix is Number 3…..
They all rank number one in my books…I grew up,, ThANKFULLY..in the 60’s with the rock and roll revolution going on.
U2, as much I do like their music very much, cannot compare with the founding fathers of rock and roll….
Many bands have made peace and diplomacy their agenda in the last 30 years…
Bono, of course, has been an A number ONE supporter of wrong doing in the world.
But let us not forget the original father of supporter of peace..
The founding father of the Boomtown Rats…Bob Geldorf.
But his band, was not a rock and roll sensation. They spoke of things that other band did not.
Most band just wanted to make music, and I am so glad they did.
But, Bless Sir Bob for starting Live Aid…. and a new awareness of major wrongdoing in this planet.
He basically started the whole Rock and Roll revolution of bands sticking their necks out for amarastice and freedom and peace and freedom back in 1984 with Live Aid. For those who could not and still cannot speak for themselves.
Since then, many bands have jumped on the band wagon (many for show, and many because they believe in justice for humanity)..
I am glad to say that Bono and U2 have made it their personal fight.
But let us not forget the original supporters that made many bands be like U2.
Let us not forget the roots of rock and roll.
i surely hope I made sense here.
Dont flame me if I did get some facts wrong.
Peace out.. my friends!
