Last night, indie pop newcomers Foster the People entertained viewers and audience members with their two-song performance set on 'Saturday Night Live.' Although the trio (which had some help from a larger backing band for their 'SNL' gig) has a huge enough sound as is, Mark Foster and company were given a little extra oomph courtesy of sax legend Kenny G.

Foster the People were introduced by host Ben Stiller, and the Los Angeles-based outfit wasted no time getting their groove on to their breakout hit 'Pumped Up Kicks.' While this song was one of the biggest of the summer, thanks to it's laid-back and breezy beat, the lyrics are actually about a crazed adolescent who steals a gun from his dad and goes on a shooting spree.

For their second performance, Foster the People treated the crowd to a rendition of their synth-laden 'Torches' track 'Houdini.' This time around, their backing band grew even bigger, thanks to a special guest solo from Kenny G. To think that just a few months ago these guys were virtually unknown within the mainstream pop scene!
