Blinking, the members emerged from the cellar room into pre-dawn light. They stood on the sidewalk, clutching their instrument cases, some smoking and all talking about the hours that had just passed.

'I'll jam with you guys anytime,' Rufus stated around his cigar. 'That was epic.'

'It was cool. You got you some licks,' the drummer said, rubbing one of his eyes.

Charles, the lead guitar, said nothing, but permitted a smile to bend his lips and honored Rufus with a slow nod.

'Mm-hmm.'

'Mmm.'

Conversation ceased. The light intensified. Rufus took a deep breath, gripped his case's handle, and turned to face the walk uptown.

'I better be off,' he said. 'My ol' lady, she....' His voice trailed off and he took a tentative step, not wanting to let go of the feeling of camaraderie he had gained, making music for the past few hours.

Charles thrust out his free hand toward him, and Rufus took it in his own. They shook, eying each other.

'Come back next weekend,' Charles finally spoke. 'Maybe we'll do it again.'
