Because of a digital malfunction the nature of which I am unequipped to explain, some of the pictures in the recent Rifftides archives have disappeared and been replaced by empty boxes. The artsjournal.com technical hierarchy assures me that the gremlins have been found and summarily executed, but their mischief remains until the Rifftides staff can repair it. That is a matter of one photo being restored at a time. The staff has plenty to do and will undertake restoration as time allows. If you are browsing the archive and disturbed by those ghostly frames, we offer the standard modern mea culpa in times of disaster large or small: we regret any inconvenience.
