Stephen Colbert’s highly-anticipated debut in David Letterman’s old spot is fast approaching, and The Late Show has just revealed the guests Colbert will welcome in his first week.

The list includes Tesla and SpaceX CEO Elon Musk, as well as Uber CEO Travis Kalanick.

That’s a lot of tech for a first week, and for a network late night program. Musk is pretty well known and always interesting, but Kalanick is probably not on many people’s radar. Uber is, of course, so it’ll be interesting to see what Colbert has up his sleeve in that regard.

The first week will only include four new episodes (Labor Day), and here’s the full lineup:

September 8:
George Clooney, Republican presidential candidate Jeb Bush
Musical performance: Jon Batiste and Stay Human

September 9:
Scarlett Johansson, SpaceX and Tesla Motors CEO Elon Musk
Musical performance: Kendrick Lamar

September 10:
Uber CEO Travis Kalanick
Musical performance: Toby Keith

September 11:
Amy Schumer, Stephen King
Musical performance: Troubled Waters

Kalanick appears to be the only non-musical guest of the night. Musk has to share his time with ScarJo – a tough act to follow for sure.
