While there was a later Fourplay album, Energy, released on SACD by Heads Up, this new SACD covered the group's initial albums released on Warner Bros. Records. I am guessing that Bob James licensed the Fourplay album to Evosound of Hong Kong for release on SACD, as he has done with his new albums and older releases. "The Best of Fourplay" is not listed on Evosound's website or online store, but it was just added to importcds.com.....
