The band may be called "funk," but there is little to no funk in this requestrocity.
If you appreciate Mario Bros., music, or the music of Mario Bros., I don't see how this is enjoyable. This is just a stumbling through the general rhythm of the Mario Bros. theme. I'm surprised they played this five times on tour without taking the 20 minutes to sit down and transcribe it. I could understand this performance if they hadn't heard the music since playing the game in 1986, but every other remixer here spends time on their work. If there is a worse piece on this website, I'd like to hear it.
