Herb Alpert and Sergio Mendes, long associated with the carefree pop music of the 1960s, are back in record stores after long absences.

Alpert broke into pop consciousness with his band the Tijuana Brass, whose song "Lollipops and Roses," from the1965 album Whipped Cream and Other Delights, found its way into millions of American homes.

Forty years after helping add exotica to the American music scene, Alpert has collaborated with heavyweights of electronic music for a disc of remixed versions of his songs. The new album is called Rewhipped.

Sergio Mendes, Alpert's Brazilian protege, is following a similar path with will.i.am, of the pop-rap group the Black Eyed Peas. The pair have updated hits by Mendes' group Brazil 66 for the CD Timeless.

In addition to will.i.am, Mendes worked with Stevie Wonder, India.Arie and Jill Scott, among others. The songs range from old classics like "Mas Que Nada" to the new "Please Baby Don't," written and sung by John Legend.
