Polygraph Lounge is like a lot of things. Rob Schwimmer and Mark Stewart, the two merry minstrels of the ensemble, cite Victor Borge, Tom Lehrer, Firesign Theatre, and the immortally anarchic '40s bandleader Spike Jones among their influences. They might as well have added Johann Sebastian Bach, who put two popular songs into counterpoint and entered them into his ''Goldberg" Variations.
But nothing today is much like Polygraph Lounge, and nothing like Polygraph Lounge would have been possible earlier, because its work depends on more than 250 years of music since Bach's day, and on modern electronics -- not only electronic instruments, but the electronic world that all of us inhabit, in which the music of the world can fill the air at a touch of a button, and everything we have heard can be simultaneously present in our memory and imagination.
