Don't be put off this release by some of the above comments or the fact that a 10 CD release is now available at less than a tenner. This disc consists of four albums only one of which is on the Avid box set, namely the Ellington songbook. Of the others, the Kern Songbook and the Warren & Youmans Songbooks are examples of Peterson re visiting these composers with his bass and drums trio. Ignore the given recording dates given for these two. They almost certainly come from later in the 1950s and are, in my opinion, far superior to the original piano, guitar and bass efforts. The remaining set, "The Count Basie Songbook" is a bit of a misnomer in that Basie did not write or co-write more than four of the tracks. It is, however, an enjoyable session and does not appear on the Avid release. In conclusion, I can thoroughly recommend this CD as good value for money and an ideal companion to the Avid release.
