HIP (Historically Informed Performance) is not so hip as it used to be. William Christie does Baroque opera with cutting edge directors. René Jacobs records a Matthew Passion with tempi that rival Furtwängler’s. The information age was what made historically aware performances possible. It did not give us all the answers. In fifty years will we have HIP performances that are more like the 16th or 17th century than they are today? And how will the information we gain then be applied? Will not the actually application of it be indelibly tied to the decade?
