He has recorded and produced music for the most renowned artists in the music industry, including Sinéad O'Connor, Musiq Soulchild, Syleena Johnson, Snoop Dogg/Snoop Lion, Jon Secada, Maxi Priest, Sizzla, Marcia Griffiths, Beenie Man, Wayne Wonder, Buju Banton, Capleton, Sanchez, Freddie McGregor, Luciano, Sugar Minott, Barrington Levy, Gregory Isaacs, Morgan Heritage, Half Pint, Tanya Stephens, Gyptian, Cas Haley, Beres Hammond, Glen Washington, Etana and Cocoa Tea, among many others.
As a teenager, McGregor began experimenting with Steely's production equipment, imitating the styles of his musical idols, Bob Marley and Clement "Coxsone" Dodd.
[7] McGregor's concept, catchy melodies and clear lyrics, enabled his vocalists to score massive hit singles during the millennial decade.
His successes with Gyptian led to similar cultural reggae hits, including Etana's politically conscious mantra, "I Am Not Afraid," Queen Ifrica's incestial-abuse condemnation, "Daddy Don't Touch Me There" and Richie Spice's post-9/11 commentary, "The Plane Land"—these songs would make McGregor's production abilities visible to major reggae labels, including New York-based VP Records, and London-based Greensleeves Records.
During his tenure with VP Records, McGregor produced hit singles for several of VP Records' most successful albums, including Richie Spice's "Gideon Boot," Etana's "Strong One," Morgan Heritage's "Mission in Progress," Beres Hammond's "A Moment in Time," Fantan Mojah's "Stronger," and Queen Ifrica's "Montego Bay."
McGregor began to embrace British Lovers Rock music in 2011, releasing romantic reggae albums, EPs and maxi-singles with Maxi Priest, JC Lodge, Carroll Thompson, Janet Kay, Adele Harley, Gappy Ranks and Roger Robin.
[12] Since the release of "How About I Be Me," and its subsequent radio airplay, McGregor made a transition toward recording pop singers on reggae riddims, employing a greater proportion of uplifting, radio-friendly lyrics and commercial production techniques.
In 2013, McGregor is preparing to release pop-reggae music from a collection of American, Canadian and European pop stars, including Musiq Soulchild, Syleena Johnson, Sinéad O'Connor, Divine Brown, Elaine Shepherd, Dru and Jesse Giddings.
In response to several internet media reports claiming him to be the son of Freddie McGregor, Kemar replied, "I don't know what else to do ... it happens here in Jamaica, it happens overseas.
In 2013, the McGregor-produced single "Radio," performed by Canadian pop-reggae singer Ammoye, was nominated for a JUNO Award in the "Reggae Recording of the Year" category.
