Base Nation

Kenny Chesney treats his first-ever live album as a celebration, collecting 29 highlights recorded at some point over the 2010s. By casting such a wide net, Chesney has plenty of room for covers and cameos in addition to the hits, but it's also telling that Live in No Shoes Nation concentrates on all the music he's made following the release of 2001's Greatest Hits. Starting with 2001's No Shoes, No Shirt, No Problems, he's hit his sunny stride, specializing in mellow beach tunes, slightly sad ballads, drinking tunes, and arena anthems, all of which are featured on this double-disc set. If the crowd noise sometimes seems a bit heavy-handed, the roar underscores how Chesney entertains on a mass scale, and that's perhaps the one revelation of the record: based on this, calling his fan base a nation isn't much of an exaggeration.

Eight years after their last studio release (2002's underperforming Da Capo), Swedish pop quartet Ace of Base return, minus original members Malin and Jenny Berggren, but with two new sound-alike vocalists in tow, Julia Williamson and Idol 2009 semifinalist Clara Hagman, for their fifth LP, The Golden Ratio. They may be synonymous with the dominant Europop scene of the mid-'90s, but with Lady Gaga pilfering their sound for recent single "Alejandro" and Katy Perry acknowledging them as a major inspiration for her Teenage Dream album, they couldn't have timed their long-awaited comeback much better.
