The Bops are Hot.

Listen to "Sister Kate." (Navigate to Songs and Lyrics; it's track 4 on the album.) Also try "There's A Girl", which is track 9.

From the All Music Guide: Purveying an utterly charming sound that borrows from folk, pop, Western swing, and early vocal jazz, Los Angeles' fancifully named Ditty Bops feature the tightly woven harmonies of Amanda Barrett (who also handles mandolin and dulcimer duties) and Abby DeWald (who also plays guitar).

From the Amazon editorial review: Los Angeles duo The Ditty Bops call upon a 20th century grab bag of musical trends for the dozen songs that make up their eccentric debut album. DeWald and Barrett employ their effortless harmonies as instruments as they sashay through an influential spectrum that spans Bix Beiderbecke’s swinging twenties, through the Hot Club Quintet of France by way of Bob Wills’ Texas Playboys, and into the contemporary experimentation of producer Mitchell Froom (Elvis Costello, Suzanne Vega).

Give the record three spins. You’ll know every song.
