After years as CFO of the World Wildlife Fund and African Wildlife Foundation, Tom Nichols stepped out of those roles a few years ago to commit to becoming a full-time musician -- going beyond work with the Gay Men's Chorus of Washington, D.C., and supporting work with other local musicians, including his partner Dan Chadburn. Nichols, who released his first solo album, Trust, last year, is the kickoff concert in a summer songwriter series at the DC Center. Saturday, Aug. 11, at 8 p.m. The DC Center for the LGBT Community, 1318 U St. NW. Suggested donation is $10. Call 202-682-2245 or visit thedccenter.org.
