Angry Birds theme song, then perhaps you should check out tonight's London Philharmonic Orchestra's video game tribute concert. The group will play more than 20 songs made famous by games like Tetris, Zelda, Call of Duty and of course, Mario Bros., as part of London's annual music festival. When asked to create the ultimate gaming remix, composer and arranger Andrew Skeet vowed to keep it old school, while giving folks the best bits of music. It's not the first time someone's paid tribute to these hits, and we're hoping it's not the last. Check out the full setlist and video after the break.
