Concept was the first time the siblings got an opportunity to work with Leon as their producer since their last really good album "Forever Yours". There were 9 tracks on the album.The majority of the tracks were written by Solar mainstays Kevin Spencer,Dana Meyers,Nidra Beard,William Shelby,Karen Elliot,Big sister Charmaine and of course one of the Greatest producers of all time big brother Leon III. Anchored by standout tunes like "Come Back Lover Come Back", Heart Repair Man,P.S. (The Unfinished Letter), I'm Gettin' Over they went on to show that they were still as special as we all remembered them being. Most of the male lead vocals were handled by James,with Pat filling in for the female leads proving that they were all willing and able to keep the groove ship fully bouyed.The album was released in the year 1981 and unfortunately was the one more album before it would all end mark.But can honestly say,if there is any way you can get your hands on a copy (I have it on wax) you will be pleasantly surprised by how good it really was.
