Pentatonix mashup of Sam Smith - La La Latch (VIDEO)

Pentatonix performed a mashup of Sam Smith songs called 'La La Latch'. It's a mix of 'Latch' and 'La La La'.

Amazing as usual.

Pentatonix were the winners of The Sing Off Season 3 on NBC in 2011.

The a capella group has since moved on to be YouTube stars and are the most successful group to come out of that reality show.

PTX VOL. III is now available for pre-order. They are also releasing a holiday album That's Christmas To Me on October 21, 2014.

“La La Latch” is a mashup of “Latch” by Disclosure ft. Sam Smith and “La La La” by Naughty Boy ft. Sam Smith.
