In Brief

* * * Rob Wasserman, “Trios,” MCA/GRP. Did the manufactured collaborations of Frank Sinatra’s “Duets” leave you unsatisfied? Bass-master Wasserman’s latest project ups the ante, as he anchors a series of sparkling threesomes for real musical interplay, crossing genres (Primus’ Les Claypool with blues-rocker Chris Whitley) and generations (Carnie Wilson reunited with her dad, Brian). Other participants of note include Elvis Costello, Willie Dixon and Neil Young.

New albums are rated on a scale of one star (poor), two stars (fair), three stars (good) and four stars (excellent).
