The members of RSS Trio will make Green Lady Lounge their home this weekend. The young Kansas City band performs from 10:30 p.m. to 2:30 a.m. on the night of Friday, August 12, from 6:00 p.m. to 2:30 a.m. on the evening of Saturday, August 13, and closes the weekend with a four-hour engagement beginning at 10:30 p.m. on Sunday, August 14. It’s precisely the type of grueling apprenticeship that transformed many aspiring local musicians into international stars during Kansas City’s jazz heyday.
