We welcome back the Sweet Sheiks, who will be presenting an upbeat mix of music that’s almost as old as the Transfer building itself, bringing jazz and pop from the teens through the 30s to your Thursday night. Sweet Sheiks is Jen Lauren on vocals, guitar, and musical saw, Aaron Johnson on tuba, Jay Allison on trombone, and Ernie Brusubardis on mandolin.

Martini Jazz Lounge, every Thursday through May, 6:30 to close. Martinis and Cosmos, $8. Cover, $0.

Next week: Jamie Breiwick Quartet
