Committed (vocal group)

Committed is an a cappella group of six male vocalists from Huntsville, Alabama, all students at Oakwood University, a historically black Seventh-day Adventist school in Huntsville. The group—Therry Thomas, Dennis Baptiste, Tommy Gervais, Geston Pierre, Robert Pressley and Maurice Staple—began singing together in 2003, inspired by another a cappella group that originated at Oakwood, Take 6.
The group won the second season of the musical competition "The Sing-Off". They won the title on the finale broadcast on December 20, 2010 broadcast on NBC, singing a vocal "a cappella" arrangement of "We Are the Champions" from Queen. 
The singing group released their self-titled album "Committed" on Epic Records.
