Perhaps you remember the groundbreaking video for Radiohead's 'House of Cards,' the James Frost-directed clip that used remote optical technology instead of actual video cameras to create a matrix image of singer Thom Yorke? Frost doesn't take such a high-tech route on the new video for Dave Matthews Band's 'Mercy,' but it's still visually compelling, featuring a patchwork collage of uplifting and heartwarming footage that was submitted by fans last month to expound on the universal message of love. In other words, you may just get goosebumps watching it.
