“Ripple” was originally the flip side of the Grateful Dead’s 1970 “Truckin’” hit. Could there be any more perfect name than Ripple Effect for a Dead tribute band? On June 28, Crossroads, 78 North Avenue, in Garwood, will host Ripple Effect with The Hepkatz opening. This room has a slew of intriguing shows upcoming including a ‘90s Tribute Fest on July 12, Deer Tick on July 13, Dueling Pianos on July 19 and Tim Barry on August 24.
