Caffé Lena, the city’s legendary music venue, will reopen on Friday, Dec. 30, with The Suitcase Junket, a roots rock one-man band who performed last year to launch a renovation campaign for the venue. During the six-month modernization effort, Caffé Lena took its programming on the road, with performances at The Grove at Neumann and some 12 other locations in Saratoga Springs.
