The Four Tops' story is one of longevity and togetherness: these Motown legends teamed up in high school and spent over four decades without a single personnel change. In between, they became one of the top-tier acts on a label with no shortage of talent, ranking with the Temptations and the Supremes as Motown's most consistent hitmakers. Where many other R&B vocal groups spotlighted a tenor-range lead singer, the Four Tops were fronted by deep-voiced Levi Stubbs, who never cut a solo record outside of the group. Stubbs had all the grit of a pleading, wailing, gospel-trained soul belter, but at the same time, the Tops' creamy harmonies were smooth enough for Motown's radio-friendly pop-soul productions. From 1964-1967, the Four Tops recorded some of the Holland-Dozier-Holland team's greatest compositions, including "Reach Out, I'll Be There," "I Can't Help Myself (Sugar Pie, Honey Bunch)," "Standing in the Shadows of Love," "Bernadette," and "Baby I Need Your Loving." The group's fortunes took a downturn when their chief source of material left the label, but they enjoyed a renaissance in the early '70s, which saw them switching to the ABC-Dunhill imprint. Regardless of commercial fortunes, they kept on performing and touring, scoring the occasional comeback hit.

One of the most popular smooth soul groups of the early '70s didn't hail from Philadelphia or Memphis, the two cities known for sweet, string-laden soul. Instead, the Chi-Lites were from Chicago, a town better known for its gritty urban blues and driving R&B. Led by vocalist Eugene Record, the Chi-Lites had a lush, creamy sound distinguished by their four-part harmonies and layered productions. During the early '70s, they racked up 11 Top Ten R&B singles, ranging from the romantic ballads "Have You Seen Her" and "Oh Girl" to protest songs like "(For God's Sake) Give More Power to the People" and "There Will Never Be Any Peace (Until God Is Seated at the Conference Table)." All the songs featured Record's warm, pleading tenor and falsetto, and the majority of the group's hits were written by Record, often in collaboration with other songwriters like Barbara Acklin.

Though now known mainly for his middle-of-the-road balladry, Neil Diamond started his career in the '60s as a Tin Pan Alley pro who turned out a string of ballsy, folk-rock-styled classic Top 40 singles that may come as a surprise to anyone who's grown up with the image of Diamond as a sensitive crooner and Vegas showman. This 2 CD set contains all of his hits, but it isn't quite the definitive package that its title suggests. His early Bang singles ("Cherry, Cherry," "Kentucky Woman," "Solitary Man") and his later Columbia material ("You Don't Bring Me Flowers," "America," "Heartlight") appear in their original versions. But his mid-period MCA/UNI hits ("Sweet Caroline," "Song Sung Blue," "I Am ... I Said") are represented by live re-recordings from 1989 and 1992. --Scott Schinder
