the two modifiers “who receives popular acclaim…” and “whose reputation declines…” 都是修饰 the kind of composer，在功能上是平行的。
并且由于表达的意思相反，是需要连接词 but 的。即便意思相同，whose前面还是缺连接词and，反正没有连接词我无法接受这个句子。。。。
它所说的描述两件事是指the kind of composer who receives popular acclaim while living and whose reputation declines after death don't describe the same thing because the first is about the composer, the second about his reputation.
