Over the past year, makeshift venues from Se?or Frog's to Bennigan's have been pushing the tables against the walls and squeezing in stages to feed our city's hunger for live music. Home to the ever-shifting roster of musicians who make up Grupo Nostalgia, the swanky nightclub Café Nostalgia has done its own double duty by clearing a space for guest artists in the hours before the house band starts to swing. The club's luxurious booths proved the perfect vantage point from which to view the Jerry-Lewis-meets-Beny-Moré antics of trovador David Torrens, while generous sightlines and dappled lights revealed pan-Latin rockers Bacilos even as dancers packed the floor. The holiday-in-Havana décor is a fabulous backdrop not only for the son-to-timba traditions of Cuban dance music but also for forward sounds such as Aterciopelados' future-lounge.
