I know I am a little late finding out about this Mash Up but it’s really well done and I am sure some people still haven’t heard of it. Sam Tsui and Casey Breves are singing Sam Smith’s “I’m Not The Only One” and Ed Sheeran’s “Thinking Out Loud” – at the SAME TIME. The outcome is remarkable and definitely worth a listen. Great idea to mash up these two enormous hits in an unusual way and of course it already went viral. Enjoy.
Here is some info about Sam Tsui… Couldn’t find much on Casey Breves.
Samuel “Sam” Tsui (born May 2, 1989) is an American musician and internet celebrity who rose to fame on YouTube. He is best known for covering songs by popular artists like Adele, Britney Spears, Taylor Swift, Justin Timberlake and Bruno Mars, as well as for his original songs, medleys, and mashups, along with his frequent collaborations with Kurt Hugo Schneider. – From Wikipedia
