March 24. The living queen of rockabilly, Wanda Jackson has one of the fiercest voices in music, an alley-cat growl that sounded capable of making her 1950s rock 'n' roll-cofounder peers like Elvis Presley, Jerry Lee Lewis, Gene Vincent, and, on a good day, maybe even Little Richard run for the hills. But the 78-year-old Jackson, who pays us a not-to-be-missed visit with this turn at Club Helsinki, has a softer side, too; her discography also boasts stacks of sweet traditional country and gospel recordings. But it's the wild and raw rockabilly of tracks like "Let's Have a Party," "Mean, Mean Man," "Fujiama Mama," and "Funnel of Love" she's best known for, and it's that era of her career that's led to a spot in the Rock and Roll Hall of Fame, a Jack White-produced album, The Party Ain't Over, and even a slot opening for fan Adele (?!). (Aaron Neville arrives March 17; Lady Moon and the Eclipse land March 18.) 8pm. $25, $35. Hudson. (518) 828-4800; Helsinkihudson.com.
