[6] AllMusic critic Richard S. Ginell observed, "by this time, like several other pianists, Guaraldi was actively exploring the new sonic horizons offered by electronic keyboards, and so he superimposes layers of electric harpsichord on most of these tracks.

But the tunes are marvelous, and since so little of Guaraldi's vast Peanuts output was ever made available, every millisecond of these jazz waltzes, bossa novas and soulful ruminations on Charlie Brown's world becomes cherishable.

"[1] Guaraldi historian and biographer Derrick Bang noted that the songs are "presented in a manner wholly unlike the quieter trio sound found on [Jazz Impressions of] A Boy Named Charlie Brown and A Charlie Brown Christmas," noting that the album contains, "the jazziest, swinging-est collection of his Peanuts themes that Guaraldi ever released."

Bang cited the arrangement of "Linus and Lucy," as "smokin'", adding that the song is "dominated by Guaraldi's percussive piano attack in the foreground, augmented by harpsichord shading in the background.

His acoustic improv bridges never have been better, making this his most vibrant recorded version of what, by now, had become his second signature tune, after 'Cast Your Fate to the Wind'."
