Retrospective: The Best of Buffalo Springfield may not be definitive, but it's a good, basic overview of the group's career, containing most of the group's biggest hits and signature songs. Yes, several worthy album cuts are missing, but as a sampler, this works quite well, offering a nice introduction to the group.

Forrest Gump (1994) is one of the most successful films ever made, winning Tom Hanks his second successive Best Actor Oscar (he won the previous year for Philadelphia) as well as claiming the Best Picture Oscar and many other awards and nominations, including several for music. A unique fable of American life from the 1950s to the 80s, the film blends comedy, drama, war, romance and groundbreaking special effects into a social and political portrait of the passing years, all seen through the eyes of the intellectually challenged but immensely likeable Forrest Gump. The soundtrack is a double album featuring 31 classic pop tunes plus a suite from Alan Silvestri's rich orchestral music, represented more completely on the companion score album.

Given the quirkiness of Neil Young's recording career, with its frequent cancellations of releases and last-minute rearrangements of material, it is a relief to report that this two-disc compilation is so conventional and so satisfying. A 35-track selection of the best of Young's work between 1966 and 1976, it includes songs performed by Buffalo Springfield, Crosby, Stills, Nash & Young, and the Stills-Young Band, as well as solo work. In addition to five unreleased songs, Decade offers such key tracks as the Springfield's "Mr. Soul," "Broken Arrow," and "I Am a Child"; "Sugar Mountain," a song that had appeared only as a single before; "Cinnamon Girl," "Down by the River," and "Cowgirl in the Sand" from Everybody Knows This Is Nowhere; "Southern Man" and the title track from After the Gold Rush; and "Old Man" and the chart-topping "Heart of Gold" from Harvest. This is the material that built Young's reputation between 1966 and 1972, although he is more idiosyncratic with the later material, including the blockbusters "Like a Hurricane" and "Cortez the Killer" but mixing in more unreleased recordings as the set draws to a close.

Buffalo Springfield's discography received the complete box set treatment in 2001, with a four-disc set filled with previously unreleased demos, alternate takes, and other rarities. In contrast, What's That Sound: The Complete Albums Collection attempts to restore the discography to how it was heard upon its original release…

The plainly named Box Set – that's the actual title – contains four CDs by a band that made only three albums in their brief lifetime. It goes without saying that this has a lot of great music, and is an essential purchase for fans of this phenomenal 1960s folk-rock-psychedelic band, containing no less than 36 previously unreleased demos, outtakes, and previously unissued mixes. It's the unreleased stuff that holds the most interest, especially since even on their outtakes, Buffalo Springfield were often superb…
