The Baltimore International Festival is this weekend…(I just found this out about 5 minutes ago) After looking at the lineup, I realized that the 70’s Disco group, Heatwave is performing tomorrow night on the Poly High School Athletic Field at 8pm…(It’s a pretty cool space, they should use it more often for concerts.) You may, or may not, remember them from such hits as “Boogie Nights” and “The Groove Line”…or because their keyboard player, Rod Temperton, is responsible for two of the greatest Michael Jackson songs of all time, “Rock With You” and “Off the Wall”…So if your in Bmore tomorrow go check out some truly legendary musicians for free.
