In an article in the Jamaica Observer (click here)Kevin Jackson covers the album charts:
Imperial Blaze had a "#12 debut on the Billboard 200 album chart. The sales impact though not as huge as his previous opening in 2005, was enough to land the set to the top of Billboard's Reggae album chart. Over on Billboard's R&B Hip Hop album chart, Imperial Blaze lit up the number three spot."
In addition the the reporting in the article, "Imperial Blaze" had an impressive #1 debut on the Billboard Rap album sales chart.
