Bluegrass musician BM, whose repertory, views on musical collaboration, and voval style influenced generations of bluegrass artists, also inspired many musicians, including A, B, C.                                                                                                                                                                                               
                                       
                               
                       
               
我稍微简化了一下题目，这个就是包含正确答案这一整句句子了。
问题1：我一直以为这段话主语是MUSICIAN BM，那么whose repertory, views on mucial collaboration ... influenced generations of bluegrass artists，also inspired many musicians就是修饰主语的定语从句，但显然这里不是，否则主语就缺少了他的谓语动词。那么whose repertory.....musicians这句话该怎么理解呢，是做什么成分？

问题2：另外我一直以为also取代and是错误的用法，因为prep indiom里 also不能替代and。那also在这里为什么可以用呢？
AND
RIGHT: We are concerned about the forests AND the oceans.
We are concerned about the forests, the oceans, AND the
mountains.
We work all night, AND we sleep all day. (note the comma before AND)
SUSPECT: We are concerned about the forests AND ALSO the oceans.
WRONG: We are concerned about the forests, ALSO the oceans.

求大神帮助，万分感谢！
顺便有没有什么SC备考群我可以加入的嘛，或者有什么K书组织，一个人学习感觉有问题也找不到人讨论啊！
