We know that Blake Shelton can make a solid full-length album, but he’s definitely onto something with these “Six Pak” EPs. Like his album “Hillbilly Bone” earlier this year, which reached No. 2 on Billboard’s Top Country Albums chart and launched the hit title track, the singer’s latest set, “All About Tonight,” is a satisfying sprint without fat or filler but packs plenty of fun. The title track is a spirited party anthem with a “tomorrow can wait ’til tomorrow” refrain that would make Jimmy Buffett proud, while “Got a Little Country” and “Draggin’ the River”-a sly murder fantasy duet with fiancee Miranda Lambert-are boot-scootin’ honky-tonk fare. On the more poignant tip is “Suffocating,” a heart-wringing lost-love paean written by Lambert and Lady Antebellum‘s Hillary Scott, and “Who Are You When I’m Not Looking” mixes humor and pathos with a sweet melody and a wry attitude. The EP concept behind “All About Tonight” may seem small, but like its predecessor, it delivers big.
