The Dave Brubeck Quartet - Time Out

Sure, most know the song Take Five but the rest of the album is great as well!

From left to right- Bill Evans. One of my all time favorites. He uses a mix between a classic Steinway piano and a fender Rhodes piano which is my favorite sounding electric piano.

Ahmad Jamal - The Awakening

Space, space, and more space.

Charles Mingus - Mingus Plays Piano

The album is notable for Mingus's departure from his usual role as composer and double-bassist in ensemble recordings, instead playing piano without any additional musicians.

And it's all improvised.

John Coltrane - Ole. Not as acclaimed or well-known as something like Blue Train, A Love Supreme, or Giant Steps, but it's still a great listen. It has such a dark and mysterious vibe to me, especially in the title track, that I dig wholeheartedly.

Thanks for the recs guys. I will surely check them out. Another album, that I have heard, that is underrated is Sonny Criss's Sonny's Dream (Birth of the New Cool): absolutely fine album, reminiscient of Horace Tapscott's big band stuff (due to him being the composer & arranger).
