从原句分析,这个句子的两个分句应该是:
they produced a new record in 1996. They celebrated the new recorde with their former time (or record?) as a real band. (与他们之前的时间(记录?)一起,他们像一只真正的乐队一样庆祝这一新纪录(的产生))。
抛开本句逻辑上是否合理不说,就纯语法而言,which 指代 the new recorde,因此从句中的with不能省略。
此处with which的用法看上去像倒装,但是为什么倒装我不能说明白。但是如果从句是which they celebrate with their.....也没有错。个人觉得。
追问celebrate with是短语搭配吗?
