DOCTOR NIGHTLIFE has serious philosophical reservations about 2 Live Crew's message, but none about their inalienable right to deliver it. The best antidote to narrow-mindedness is broad exposure. Onward and upward: FRIDAY
SECOND WIND --
Hometown girl Stacy Lattisaw had her first Top 40 hit when she was 13, but now, at the ripe old age of 23, she's probably feeling like Tracy Austin watching the Tiffanys and Tracy Spencers -- the Grafs and Capriatis -- rocketing to fame. That's okay: A well-rounded voice, like a vintage wine, mellows with maturity (through Sunday at Blues Alley; $18; 337-4141). SATURDAY
PARADISE REGAINED --
Doctor Nightlife was so excited about the Bill Kirchen/Daryl Davis/Ron Holloway jam at Joe's Record Paradise in Aspen Hill that she went a week early. So Take Two and call us in the morning. The free concert starts at 1:30, and if you want a second opinon, call Joe and ask him (598-8440). SUNDAY
HOMEY COMPANIONS --
In a way, they are America's two great men of radio: Chet Atkins, whose jazz-informed electric guitar has been the most sophisticated conduit of country music for 35 years, and Garrison Keillor, whose "Prairie Home Companion" reestablished the fireside intimacy of early radio entertainment -- and introduced Atkins to another generation of admirers. They appear together at Wolf Trap (reserved seating $25 and $30, lawn tickets $15; 432-0200).
RE-SUN TO BELIEVE --
Remember how you used to sit around giggling and making up fulsome titles for country music tearjerkers? Mark Collie still has a weakness for that kind of punny fun ("Where there's smoke, you'll find my old flame," "She wants something with a ring to it," "What I wouldn't give was more than she could take") but his V-8 rockabilly yearnings and Johnny Depp spitcurl could reestablish the Sun Records-style sex symbol. His supporters are an impressive testimonial in themselves -- among musicians on his new "Hardin County Line" album are James Burton, Barry Beckett, Marty Stewart and Mac McAnallly (at Zed in Alexandria; 768-5558). MONDAY
YOUNG MAN WITH A HORN --
A trumpet can be an insinuating as well as cocksure instrument; and Randy Brecker's particular brand of smoky savoir-faire has provided unusual self-possession to scores of rock, jazz, fusion and blues records -- Steely Dan, John Mayall, Larry Coryell, Chaka Khan, Carly Simon. If he had only ever recorded the melancholy soliloquy in "Meeting Across the River," he would still have a place in rock history. Brecker performs two sets at Blues Alley ($17.50; 337-4141). TUESDAY
TINSLEY TOWN --
Georgia's white blues guitar phenom, Tinsley Ellis, wails into the Grog & Tankard to show off the licks that made him on the Hot Rize circuit (and have earned him a slot on the increasingly sure-footed Miller Genuine Draft blues network). You gotta like a guy who still has the first broken guitar string he ever got -- courtesy of B. B. King, right off Lucille's neck ($7; 333-3114). WEDNESDAY
MR. MELLOW --
Maybe we're just weird, but those late-night advertisements scrolling up a 30-year list of hits by velvet-voiced Roger Whittaker (strumming his guitar and looking sincerely into our eyes) gives us the strangest urge to pack up some roast-chicken sandwiches, put on our string ties, take a seat at Wolf Trap and nod gently in appreciation ($13 to $25; 432-0200).
