"Jivin' with Jarvis"

Vibraphonist Lionel Hampton made some great records during the late 1930s and 1940s, and this is an especially good one featuring the Nat King Cole Trio.  Listen to those low-register A-flats that Cole plays on the piano right near the start as the rhythm section enters.  And hear Cole's graceful 16-bar solo at 1:27!  You can learn a lot from listening closely to the different rhythm section riffs, backgrounds, and exchanges behind the solos.  Here's Cole's trio with Ida James:

...and here's Hampton from about 14 years later, playing his composition "Midnight Sun."

Al Jarvis was a radio DJ (and, later, TV host) in Los Angeles.
