Who Knows starts out with a very strong guitar interlude, with the drums kicking in a few seconds later. This continues on and you can hear the raw power of the guitar as it is accompanied by continuous cymbals and a steady drum beat. When the singing starts - about a minute into the song - the words are almost unintelligible; with a second singer echoing the lyrics of the first. This song mainly focuses on the guitar solos and rhythms.
Great song to listen to if you're looking for more powerful guitar solos.
