Season 7 of 'The Voice' kicked off in a big way Monday night, Sept. 22, with all four judges - Gwen Stefani, Adam Levine, Blake Shelton and Pharrell Williams - working together for a rousing performance of 'Hella Good.'

In addition to being a fun, upbeat song, the 2002 hit also has a history with two of the judges. The track was originally recorded by Stefani's band, No Doubt, and was co-written by Pharrell.

With Stefani on vocals, Pharrell on drums, Levine on guitar and Shelton on backup vocals, the four judges looked so cohesive together, it's clear that we are in for a great season ahead of us.

The first night of 'The Voice' blind auditions featured some spectacular performances by unknown talent. Bryana Salaz blew the judges away by taking on Ariana Grande's 'Problem.' A young TSA agent named Damien gave an emotional performance by singing 'It's So Hard to Say Goodbye to Yesterday.' James David Carter from Atlanta, Ga. had all four judges fighting for him after singing a country version of Tony Rich's 'Nobody Knows.'
