Neville sank into a seat and watched them go. Then he began to take stock of the playhouse. The seats were comfortable and commodious, evidently having been designed to hold patrons clad in heavy-dust space-suits. The auditorium was almost circular, one semi-circle being taken up by the stage, the other by the tiers of seats. Overhead ranged a row of boxes jutting out above the spectators below. Neville puzzled for a long time over the curtain that shut off the stage. It seemed very unreal, like the shimmer of the aurora, but it affected vision to the extent that the beholder could not say with any certainty _what_ was behind it. It was like looking through a waterfall. Then there was eerie music, too, from an unseen source, flooding the air with queer melodies. People continued to pour in. The house gradually darkened and as it did the volume and wildness of the music rose. Then there was a deep bong, and lights went completely out for a full second. The show was on. Neville sat back and enjoyed it. He could not have done otherwise, for the sign on the hull had not been an empty plug. It was the best show in the void--or anywhere else, for that matter. A spectral voice that seemed to come from everywhere in the house announced the first number--The Dance of the Wood-sprites of Venus. Instantly little flickers of light appeared throughout the house--a mass of vari-colored fireflies blinking off and on and swirling in dizzy spirals. They steadied and grew, coalesced into blobs of living fire--ruby, dazzling green, ethereal blue and yellow. They swelled and shrank, took on human forms only to abandon them; purple serpentine figures writhed among them, paling to silvery smoke and then expiring as a shower of violet sparks. And throughout was the steady, maddening rhythm of the dance tune, unutterably savage and haunting--a folk dance of the hill tribes of Venus. At last, when the sheer beauty of it began to lull the viewers into a hypnotic trance, there came the shrill blare of massed trumpets and the throb of mighty tom-toms culminating in an ear-shattering discord that broke the spell. The lights were on. The stage was bare. Neville sat up straighter and looked, blinking. It was as if he were in an abandoned warehouse. And then the scenery began to grow. Yes, grow. Almost imperceptible it was, at first, then more distinct. Nebulous bodies appeared, wisps of smoke. They wavered, took on shape, took on color, took on the appearance of solidity. The scent began to have meaning. Part of the background was a gray cliff undercut with a yawning cave. It was a scene from the Moon, a hangout of the cliffdwellers, those refugees from civilization who chose to live the wild life of the undomed Moon rather than submit to the demands of a more ordered life.
