Pipe organs are not, in general, portable instruments. The venues for organ recitals using those instruments are thus the churches, theatres, or halls where the organs are housed. Some instruments of about a century ago were built to be listened to while strolling, such as those at the Wanamaker department store in Philadelphia or the museum of San Francisco's Palace of the Legion of Honor, which is not heard to best advantage from any one spot.
However, with some organs the console is portable to a limited extent (such as, for example, being attached to a platform that can be raised or lowered, which is often the case for theatre organs, but rarely the case for church organs, with the exception of the Crystal Cathedral organ in California. Where this is the case, the console is moved for the recital so that the audience can see the organist playing.
