Whit Dickey Quartet Root Perspectives Tony Malaby, tenor saxophone; Matthew Shipp, piano; Brandon Lopez, bass; Whit Dickey, drums TAO Forms CD   Drummer Whit Dickey has put together a formidable quartet for Root Perspectives, a release on his TAO Forms label. Joining Dickey are tenor saxophonist Tony Malaby, pianist Matthew Shipp, and bassist Brandon Lopez, all stalwart players of ecstatic jazz. While the musicians have worked with each other in various contexts, this particular configuration is new. They find their footing fast.    Malaby is versatile in his approaches to playing. Howling high notes, skronk squalls, and chromatic scalar work
