Blues fans are always looking for different players, people who can carry the torch and build on tradition. Sorry, but young white boys like Jonny Lang, who rip off old white boys like Stevie Ray Vaughan, are not the answer. Will New Orleans's Mem Shannon fill those shoes? Who knows? But we do know this: On his third disc, 1999's Spend Some Time with Me, Shannon continues on his journey showcasing an unusual writing style that incorporates heartfelt vocals with funk, jazz, and rock rhythms and a blue soul. Shannon makes the circuit around town, performing with "Spider" John Koerner and Dave "Snaker" Ray (see "Music," page 89) at Alligator Alley (2079 N University Dr., Sunrise; 954-568-0175) Friday night at 9:00; cover charge is $12. Shannon flies solo at the Rhythm Room Café (239 Sunny Isles Blvd., Sunny Isles Beach; 305-919-8080) on Saturday; call for cover charge and showtime.
