Quincy Jones' ''joint'' is a big, clean house where bop begets rap begets soul, and all-stars like Bono, Stevie Wonder, and Ray Charles are bathed in swirly, studio-crafty splendor. Q's Jook Joint is a gentle, wild ride, from the bebop phraseology of ''Moody's Mood for Love'' to the pop-funk of ''Rock With You'' to the sultry simu-love closure of ''Grace.''
