Black and White grainy footage for the intro, ideology behind this could connote it is representing some form of social issue, perhaps racism?
Signifiers of a rock band: long hair, leather jackets, tattoo's, smoking, bandana, studs, male jewelry, etc.
Performance style of video, rehearsal? no audience. Good use of behind the scenes footage.
Sexual intent connoted between band members and attractive females, eye contact, cheeky smile.
Perhaps song title and lyrics refer to love interest, Sweet Child O' Mine, maybe they are flashbacks? Possibility that it is a narrative form of music video.
