3/27/13: Despite a bit of radio silence from the band on the music front, U2 frontman, Bono, made headlines earlier this month after delivering a TED Talk about ending world poverty. This isn't the first time the rocker has taken the stage at the famed conference: in 2005, he gave a speech which outlined the number of orphan deaths in Africa due to poverty-related illnesses and lack of medicine. Fortunately, he had some good news at his most recent talk, and shared with the audience that the number of people living in extreme poverty has steadily declined. He even went so far as to say that in 2030, no one in the world will be living on less than one dollar a day. Despite the positive stats, Bono still urged those in attendance at the conference to not become complacent: "We can't get this done until we accept that we can get this done." The 52-year-old Irishman certainly has a way with words.

Besides Bono's usual philanthropic contributions to society, the rest of his bandmates are also stepping up to the plate. Earlier this year, the entire troupe donated the profits from their 2009 Dublin show (as part of their massively profitable U2360 tour) to help a local charity. Music Generation - a charity based out of Dublin which provides music education for local-area youths - received 4.9 million euros from the band, as well as a promise that they'll work with the foundation in 2014 to ensure it helps a new generation of musicians.

U2 has come a long way since 1976, when Bono, The Edge, Adam Clayton and Larry Mullen Jr. formed their post-punk high school band in Dublin, Ireland. Over the past decades, U2 has developed a cult-like following with its exhilarating sounds and powerful, socially-charged lyrics. The band has released 12 studio albums to-date, with sales topping 150 million records worldwide. Among the projects were the 1987 breakthrough, 'The Joshua Tree,' and the 1991 effort 'Achtung Baby.' It was around this time that the group also integrated various influences like alternative, dance punk and industrial rock into the 'Zoo TV Tour,' with the elaborately staged event playing to arenas and stadiums around the world from 1992 through 1993. When it wrapped, U2 had done 157 shows, beginning in Lakeland, Florida, and eventually ending in Tokyo, Japan. Indeed, the band has truly come to embody pop-rock superstardom in the modern era. U2, with 22 Grammy wins, is best known for its live performances which feature The Edge's echoing guitar chords and Bono's passionate, muscular vocals.

No matter the venue, a U2 tour stop is packed to the brim as their music magnetizes thousands of fans. That was never more evident than during the U2360 Tour, with its 360-degree in-the-round staging, a massive four-legged supporting rig nicknamed 'The Claw,' a rapt attention to musical detail and an ambitious schedule that covered three continents, 100 shows and several years before winding down. It ended with a final gross of $736,137,344 and a total attendance north of 7 million. All of it came in support of the band's most recent album, 'No Line On the Horizon,' which bowed in February 2009 after two years of recording sessions and a full crew of engineers, mixers, drum, guitar and studio techs. It contained Bono's rally cry to the fans: 'Let's shout into the darkness, squeeze out sparks of light.' With no projects currently on the horizon, the band members are dedicating themselves to various philanthropic causes, including Amnesty International, Product Red and The Edge's Music Rising initiative.
