I've read that River and his band Aleka's Attic played at the Wetlands Preserve nightclub in New York City on a few different occasions. According to a person who auctioned off the 4 song Aleka's Attic cassette (Across The Way, Too Many Colors, Gold Mine and Blue Period) a while back, they purchased the cassette while attending a concert at Wetlands in 1989. I believe that the photos below were taken in March 1991.

"When RIVER PHOENIX asked us to come hear his band ALEKA’S ATTIC at New York’s funkiest club, Wetlands, we were totally cool about it and only got there an hour early.  But soon the joint was jammin’ with River’s environmentally hip pals, like LISA BONET and MARTHA PLIMPTON, there to groove to the folksy tunes that he and sister Rain sang.  At the after-bash, River said of his music, “I want to wake up the masses.” But by 4:00 A.M. we were all running on empty, ‘cept LILI TAYLOR, who kept raving about the band, “They’re so brave, so fearless, I loved it.” We dug it, too but for the next gig, Rio...could you lose the ‘burns?"
