Well, it does exactly what it says on the box. The 57 tracks on this 'Magic Bus' compilation run from the late 1960s to the early 1970s, but, with remarkable perspicacity, the compiler has mixed them up very cleverly.
The CDs are called 'Turn On', 'Tune In' and 'Drop Out' and the songs on each one reflect, more or less, their monikers. Thus, on CD1 Scott McKenzie rubs shoulders with Barry McGuire, CD2 is full of singer-songwriters; Dylan, Cat Stevens and the like; whilst CD3 rocks it up with STEPPENWOLF and Cream.
What this collection is selling is nostalgia and it does it very, very well. Anyone who grew up through the years in question will remember every one of these songs and probably sing along with them too. It has to be said that there are two major omissions though, there is nothing by either The Beatles or The Rolling Stones. Down to licensing presumably. That said, this is an absolutely classic collection that has been selected with extreme care and, dare it be said, love.
