Having noted that Al had been trying to sing like Jackie Wilson, Sam Cooke, Wilson Pickett and James Brown, Mitchell became his vocal mentor, coaching him into finding his own voice. Before releasing his first album with Hi, Green removed the final “e” from his name. Subsequently, Green released Green Is Blues, which became a moderate success. Green’s follow-up album, Al Green Gets Next to You, featured Green’s hit R&B cover of The Temptations’ “I Can’t Get Next to You”, recorded in a slow blues-oriented version. The album also featured his first significant hit, “Tired of Being Alone”, which sold half a million copies and was certified gold, becoming the first of seven consecutive gold singles Green would record in the next couple of years.
Green’s next album, Let’s Stay Together, solidified his place in soul music with the title track becoming his biggest hit to date, reaching number one on both the Billboard Hot 100 and R&B charts. The album became his first to be certified gold. His follow-up, I’m Still in Love with You went platinum with the help of the singles, “Look What You Done for Me” and the title track, both of which went top ten on the Hot 100. His next album, 1973’s Call Me spawned three top ten singles including “You Ought to Be with Me”, “Call Me (Come Back Home)” and “Here I Am (Come and Take Me)”. Green’s album, Livin’ for You, released at the tail-end of 1973, became his last album to be certified gold.
In addition to these hit singles, Green also had radio hits with songs such as “Love and Happiness”, his cover of the Bee Gees’ “How Can You Mend a Broken Heart”, “Simply Beautiful”, “What a Wonderful Thing Love Is” and “Take Me to the River”, later covered successfully by new wave band Talking Heads and blues artist Syl Johnson. Green continued to record successful R&B hits in the next several years including “Livin’ for You”, “Let’s Get Married”, “Sha-La-La (Makes Me Happy)”, “L-O-V-E (Love)” and “Full of Fire”. By the time Green released the album, The Belle Album in 1977, however, Green’s record sales had plummeted, partially due to Green’s own personal issues during this time and his desire to become a minister. His last Hi Records album, Truth n’ Time, was released in 1978 and failed to become a success. Two years later, he left Hi for Myrrh Records and recorded only gospel music for the next decade and a half.
