Watch Bono: Waiting on a Saviour

Bono is the charismatic frontman of the band U2. The iconic Irish musician is renowned for his expressive vocals as well as philanthropy and activism for human rights and social justice. He has often utilised his dedicated fanbase and musical talent to raise money and awareness for various social causes. Some people criticise Bono's activism as being tokenistic due to his cooperation-friendly campaigns, tax avoidance and lavish lifestyle. Others hold his charity work in great esteem and believe that he deserves credit for the impact he has had on issues such as Aids prevention and debt relief. Either way, Bono found a way to mix music with activism that elevated his stardom to new heights. U2 have released 14 studio albums and is one of the world's best-selling music artists. They have won 22 Grammy Awards, more than any other band, and were inducted into the Rock and Roll Hall of Fame as soon as they were eligible. U2 is a band with an incredible career trajectory and their longevity has led many to regard them as one of the biggest bands in the world, they have sold an excess of 170 million records, and are still producing and writing new music. Alongside his bandmates, Bono's rise from a small-town Irish kid to selling out stadiums worldwide leaves no doubt that he has solidified a legacy before he's even retired from the music industry.
