In case you didn't realize it, VH1 thinks you oughta know who Sam Smith, Mary Lambert, and Bleachers (led by Jack Antanoff) are. And if you have been living under a rock this year, you might have missed Smith's debut album, In the Lonely Hour, which rocketed to the top of the charts earlier this summer, or Lambert's first solo album since first appearing on Macklemore and Ryan Lewis' "Same Love." But of course, we know you are up to date on your favorite musicians.

Last night, these artists celebrated a fantastic year of music during the network's annual You Oughta Know in Concert special, which gathered together this year's alumni. Joining them on stage were Tove Lo, Aloe Blacc, and Taylor Swift's touring buddy Vance Joy. Check out a few of our favorite performances below:

Smith brought down the house with a near-flawless live rendition of "I'm Not the Only One."

Meanwhile, Lambert was cute as ever singing the first single, "Secrets," from her debut album, Heart On My Sleeve.

And Antanoff and crew had fun performing the feel good, indie pop hit, "I Wanna Get Better."
