:You may want to read the guidelines on notability and verifiability. All articles on Wikipedia require at least two reliable and independent sources to meet the criterion for notability. Without these the article may be challenged, and even removed in some cases. The official site is not suitable as it is not independent, although it is a good resource once the notability has been established. Sites such as Allmusic are more suitable and would be acceptable as one of the two sources. Note that user-submitted databases, including this encyclopaedia, are not considered reliable so websites like Discogs are not suitable. It can be hard to grasp at first, but you'll start to recognise reliable sources after you've been using them for a while –
