That's What is an album by the American steel-string guitar artist Leo Kottke.

[1] It is distinctive in its jazzy nature and "talking" songs ("Buzzby" and "Husbandry").

The Orlando Sentinel wrote that "Kottke's eccentric poetics and monotone Lou Reed-style of delivery make 'Buzzby' and 'Husbandry' the strangest moments on That's What.

"[6] AllMusic stated: "Leo Kottke has always been a highly idiosyncratic guitar player whose music is infused with his wry sense of humor.

That's What is no exception, with Kottke's guitar work drawing from jazzy, blues and folk sources... Tying it all together is Kottke's fine guitar playing, as nimble and as quirky as ever.
