Despite the 1964 top-20 status of “I Wish You Love,” Gloria Lynne is absent from nearly all jazz guidebooks. Her delivery is straightforward and slightly sappy, and she may not exhibit the scatting tics considered innovative by the critical elite, but the now-65-year-old singer’s beautiful contralto has nevertheless gained her a dedicated following. While her discography is considered maddeningly inconsistent even by supporters, on the ’40s orchestral standards, ’50s lounge pop, and ’60s R&B gathered on Golden Classics, Lynne’s husky tone projects a sensual power that elevates each genre above mere melodrama. Tonight and tomorrow at 9 & 11 p.m. at Takoma Station, 6914 4th St. NW. $15. (202) 829-1999. (Steve Kiviat)
