On "50 St. Catherine's Drive," his solo posthumous 17-track set, Gibbs' searing vocal vulnerability is made all the more poignant given that it is his final album. Gibb, already ill, hoped to finish the song with his brother Barry, but died nine months later from cancer before they had the opportunity. Gibb, who wrote or co-wrote every song here, was affected deeply by the 2003 loss of his twin, Maurice, and much of the album's mainly mid-tempo material deals with loyalty and love that death doesn't diminish.
