The Louisville Leopard Percussionists are a non-profit community organisation founded in 1993 which relies primarily on donations to survive. The group is made up of more than 60 students between the ages of 7 to 14 who are taught how to work together and create clever covers of unique songs.

The group has previously covered Led Zeppelin's ‘Kashmir’, ‘Immigrant Song’ and ‘The Ocean’. In February the band were given the ultimate shoutout when Jimmy Page shared their cover of ‘Kashmir’ on Facebook writing ‘Too good not to share. Have a rocking weekend!’
