"I'd say we do reach somewhat of a younger audience, but I think for the most part that younger audience is picking our music up from a brother or sister or even parent, who is turning them onto the band"

Alex Lifeson's quote recommends that Rush, the band he is a part of, has a diverse target market. While they do have a younger target market, it is likely that this target market is being presented to the band via an older member of the family. This could be a sibling, sibling, or moms and dad, that is introducing the younger generation to the songs of Rush. This can be since the older family member is a follower of the band, or due to the fact that they want to share their love of songs with the younger generation. It is most likely that the older member of the family is introducing the younger generation to Rush because they think that the songs is worth paying attention to which it will certainly be appreciated by the more youthful generation.
