@sleepside great choice with the Lupin samples!
This was a show I used to always try to catch growing up, but could never get the title of (before the cable boxes had programming guides), and then it got replaced in the lineup. This may have fallen under Toonami, but the memory is a bit blurry. It’s a lesser known anime, The Big-O, and was played on the same late night time slots (If I remember correctly the order was: Samurai Champloo > Cowboy Bebop > Big O), and was like a fusion of Robots/ Batman, and filled with lots of big scores and jazzy elements.
Here are some heavy lines from the show:

Also, since we are on topic, I’m not sure if it would be possible to summon the ultra-talented @JonMakesBeats to please explain the sample origins used to create this classic set, but any insight would be absolutely marvelous!
