Because their instrumentation of vibes-piano-bass-drums mirrored that of the contemporaneous Modern Jazz Quartet, one of the finest and most celebrated jazz groups of all time, the Mastersounds may have been somewhat overlooked. Moreover, the Mastersounds' best-known members, vibist-arranger Charles "Buddy" Montgomery (b. 1930) and bassist William "Monk" Montgomery (1921-1982), who pioneered the electric bass in jazz, were the younger and older brothers, respectively, of Wes Montgomery, merely the greatest jazz guitarist of the post-bop era. (The ensemble was completed by drummer Benny Barth who, like the Montgomerys, was from Indianapolis, and pianist Richie Crabtree.) Still, the West Coast foursome's coolly soulful, tastefully-arranged approach won them their share of fans, as well as the 1959 Down Beat Critics' Poll for Best New Small Group. This disc combines the Mastersounds' final two LPs, both recorded in 1961; each is filled with, for the most part, the tuneful, effervescently swinging standards and gossamer ballads for which they are fondly remembered.
