Backstreet Boys 'In A World Like This:' On Album Release Date, WATCH Boy Band Perform 'Show 'Em (What You're Made Of)' and 'In A World Like This' on Jimmy Kimmel [VIDEO]

Backstreet Boys' long-awaited comeback album In A World Like This was released yesterday (July 30), after weeks of teasing and anticipation from the boy band and their dedicated fan base. To celebrate the "I Want It That Way" band's seventh American album, BSB took to Jimmy Kimmel Live! to perform two songs from the record.

The quintet began the show's performance with album track "Show 'Em (What You're Made Of)." As has been the trend for live BSB performances, the veterans prove that they still have the vocal chops 20 years in to their career. Each member's solos simply soared, particularly AJ McLean's heartfelt opening. As Backstreet Boys are best known for, the harmonies on the ballad track were as tight and rich as the studio version.

After BSB finished the song, Kevin Richardson revealed the inspiration for the song: his and McLean's children! McLean's adorable was then brought out on the stage, donning protective headphones and looking simply adorable.

As they've been apt to do, the band simply nailed the critically acclaimed track, with its soaring vocals and upbeat instrumentation and message. Nick Carter and Brian Littrell opted to play guitars on the song, showcasing their different musical abilities.
