Arcade Fire and John Mayer have licensed top hit songs to help support Haiti relief efforts.  Both have contributed big songs to upcoming commercials and ads on television.

The Haiti relief effort has garnered a huge celebrity and musician helping of support, and don’t think for a second the indie rock scene wouldn’t do their part for the cause.  Wilco have released two separate concerts for download on their official site in exchange for a donation.

Singer-songerwriter James Taylor will be showering the people of Haiti with much needed medical aid after the devastating earthquake.  He is joining Kate Markowitz, Arnold McCuller, Boston Symphony Orchestra cellist Owen Young and his wife, Kim, to perform a benefit concert at The Mahaiwe Performing Arts Center in Great Barrington, Mass. this upcoming Friday.

Over the years, artist collaborations have become run-of-the-mill; it’s not often that one stumbles across an album without a track featuring a guest artist. One such collaboration is in the works, but this one has come about as a financial aid gesture in a time of catastrophe. In light of the recent earthquake that ravaged Haiti, Jay-Z and U2 will together record a song to benefit the people of Haiti.

In a complete turnaround from what most would expect from these raucous pranksters, blink182 have released an exclusive t-shirt to aid the victims of the recent earthquake that devastated much of Haiti. All proceeds from the sales of this shirt will go to the Red Cross.
