by Scott Yanow This LP is one of five that has been reissued by Mosaic in a three-CD box set. For the jam session date altoist Lou Donaldson has a duet with organist Jimmy Smith on "I'm Getting Sentimental over You," and together they match up forces in a sextet with trumpeter Donald Byrd, Hank Mobley on tenor, guitarist Eddie McFadden and drummer Art Blakey, playing lengthy versions of Mobley's "Groovy Date" and Duke Ellington's "I Let a Song Go out of My Heart." All of the Jimmy Smith jam sessions are easily recommended to fans of straightahead jazz; get the Mosaic box.
