A 20-year-old man battling brain cancer has a very special wish this Christmas: to see Metallica. Trevor Gilbert has been battling a terminal and rare form of brain cancer for five years. Being a huge Metallica fan, Gilbert says that he would love to meet the band or at least chat with them online. Gilbert says that Metallica have a song for every mood. “If you’re mad, there’s a song for that. If you’re sad ,there’s a song for that. If you just want to jam out, there’s a song for that,” he says. Friends, family, and even Metallica fans have been supportive of this goal, even sending him memorabilia from around the world.
