Rockers Linkin Park are giving hands-on help to the victims of Hurricane Katrina - by offering to build a house. The band - which already donates $1 (GBP0.50) of its Projekt Revolution Tour ticket sales towards the construction of homes for low-income families in the Gulf Coast - has launched an online competition named after single What I've Done to recruit fans to help them build a new home in the areas affected by the 2005 storms to benefit an in-need family. Fans wanting to help construct the building alongside Linkin Park must make a two-minute video explaining what the entrant has done to improve the world. Linkin Park bassist David 'Phoenix' Farrell says, "We will help build (the home) alongside the family that will move into the house. "We hope to remind people that there is still a lot of work to be done." Entries must be submitted to contest@musicforrelief.org by 29 September (07), reports MTV.
