The lack of good music (choice A) may help account for older bands making a comeback, but this is not the best explanation. More convincing is the notion that older bands were able to blend their old sounds with new sounds to appeal to a wide audience – people who enjoyed their older music and people who enjoy the sounds of contemporary music. This would help explain their renewed popularity, because they still have a core of older fans as well as a large contingent of newer fans (younger listeners who were not necessarily familiar with their older music). Choice C is incorrect because a nostalgia for the 1960s and 1970s would mean the bands’ older music would be in demand, not their new music. Choice D is incorrect because this does not account for their lapse into “relative obscurity.” Choice E is incorrect for the same reason as c – if a new generation of listeners discovered classic rock, then they would be more interested in the bands’ older work.
