consertgoer=consert（音乐会）+goer
substitute n.替代者，替代物，替补（运动员）v.（以……）代替，取代
substitute A(for B) | substitute B (with/by A)以A替换B
Margarine can be substituted for butter in this recipe.做这道菜可以用人工黄油代替黄油。
Butter can be substituted with margarine in this recipe.做这道菜可以用人工黄油代替黄油。
句式：定语从句+宾语从句，who reply that recordings are no substitute for live performance是定语从句，修饰concertgoers；concertgoers的谓语是are（+表语missing the point）；reply that后加宾语从句that recording are no substitute for live performance
翻译：那些回应道唱片不能现场演出的忠实的音乐会观众没抓住重点。
