It's strange that a band with a song as immediate as "All Right Now" is a bit of an acquired taste, but it's the truth. Free was a powerful, majestic hard rock band at their peak, but they were also a little obtuse; a lot of their power came from their playing, and their songwriting was epic, but often elliptical. As such, they're for hard rock connoisseurs – a band who gained a spirited, dedicated following largely because they took devotion to unlock their treasures, especially in the years following their breakup. For those fans, the five-disc Songs of Yesterday is a godsend. This is not a box for listeners with less than a consuming interest in the band (even if you think you want total immersion in Free, this will not be as effective as purchasing each of their albums) since this contains a wealth of unreleased material. Very few of the tracks are actual album tracks, most are alternate mixes or alternate versions, plus there are a lot of live tracks in the mix, as well.
The frustrating thing about smooth jazz isn't an absence of talent or chops; actually, there are plenty of smooth jazz musicians who have chops galore even though their studio recordings don't reflect that. At smooth jazz concerts, it isn't hard to find artists who take a lot more chances on-stage than they do in the studio. But taking chances in the studio isn't conducive to airplay on commercial smooth jazz/NAC radio stations, which is why so many generic, unimaginative smooth jazz recordings have been flooding the market since the 1980s. Walter Beasley has certainly given listeners plenty of generic, unimaginative recordings over the years, but not everything he records is without merit – and Free Your Mind does have its moments.
