There are multiple bands with the name “2012”:

1) TWENTYTWELVE began as an idea and has now resulted into a band that cannot be ignored. 2012 consists of 5 members, Rudy[Vocals], Christian[Lead], Josh[Rhythm], Joaquin[Bass] and Nick[Drums]. All of whom are bound by the same purpose, to enlighten the ignorant and to frighten the god-fearing. Dwelling in Southern Cali, 2012 has developed a strong core following of some of the most ruthless, sadistic fans across the southland which makes the live shows all the more entertaining. Having just started in mid 2008, 2012 aims to compose some of the most vicious, unrelenting tunes that cuts you lose from all your restraints and drives you to show your true self. With their ear punching Vocals, Obese Guitar sound, and Impacting Drums, Twenty Twelve has gained a great deal of momentum starting strong in 2009 and now every intention to go full speed and never looking back.

2) 2012 is a romanian hip hop band. The members of the band are Aforic, ADN, SubSapte and Sagace Snephrue. In November 2009 they released the first album.

3) 2012 (established in 2005) is the result of 20 years of musical experience on many levels. Ever since he was born Lewis Hurrell has always been very sensitive to sound. At the age of eight he was given a small keyboard, it was only about a foot long with around 20 keys built into it. After figuring out what notes sounded good together he started piecing together songs. About a year later he was lucky enough for his family to buy a regular sized piano which expanded the world of music for Lewis. He hadn't ever performed before and when he was given the opportunity to play for a benefit in New York City he jumped at the opportunity. Playing in front of all those people and seeing the looks on their faces was a very powerful thing for a 12 year old piano player to see and feel. Lewis then after continued to make more and more music, learning from his mistakes and growing from them. He never took any lessons. It wasn't until the end of his senior year in High School that Lewis started to take off on his musical career. Until that point he had been involved in a serious relationship for over a year with a person he truly could say "I love you" to. When she went away to college they had to say goodbye. It was at this very moment that Lewis knew what he wanted to do with the rest of his life. Soon after this time, Lewis and a co-worker created the Indie label TwentyTwelveRecords featuring 2012 as the artist and released an album entitled Vision. Since the first album Lewis has been working on 14 new songs for his second full length album entitled " Peter's Son" (a tribute to his late father) which will be released in December of 2006, and recently working on songs for an upcoming third album which will be the first album of 2012 to have songs with vocals embedded in them.
