Output/Input was formed by Melvin Lee Davis, an esteemed bassist, composer, producer, and arranger who also happens to be Musical Director for 10-time GRAMMY award-winning 'Queen of Funk', Chaka Khan, who he still regularly tours with. He has also recorded, toured and worked with legends of Soul and Jazz, including George Benson, Lee Ritenour, George Duke, Will Downing, Lalah Hathaway, Patti Austin, Ledisi, and Angie Stone among many others. Davis' musical pedigree is also in evidence as co-writer of 'Soul Train's A Comin', the theme song for Don Cornelius' legendary weekly television show 'Soul Train'.

Lead vocalist Antonio McLendon has worked and performed with James Ingram, Tata Vega, Gladys Knight and Donna Summer, and features on 'Someone I Used To Love, 'Smilin' Faces', and 'I'm In Love', which received rotation plays at radio last year. 'Smilin' Faces' is a hit at UK Soul radio right now. 'Here We Go Again' is also still getting radio play and features the vocals of Audrey Wheeler-Downing, who has worked with Unlimited Touch and Chaka Khan, and Brent Carter, the current lead singer of AWB and previous to that, Tower Of Power. 'Doin' Alright' features vocals from O'Bryan, who Davis worked with extensively on his albums for Capitol. This is a re-recorded version with added horns and strings, co-written by Melvin, that originally appeared on the album of the same name in 1982. Also on vocals is Katie Holmes-Smith, a globally sought-after singer, who backed Adele on her world tour as well as currently performing with her for the duration of Adele's residency at Caesar's Palace in Las Vegas.

Band co-founders, known as the Triple H Horns, comprising Nick Mead (trumpet), Jacob Shaw (saxophone) and Patrick Hayes (trombone), are an in-demand horn section for artists such as Christina Aguilera, as well as composers and producers worldwide. They initially met Melvin Lee Davis through their work with Chaka Khan. The ensemble is completed by members Jay Williams (drums), Adam Kovacs (percussion) Kanghyun Bu (guitar), Daeun Kim (keyboard), and Jesse Milliner (keyboard).
