They need an Uber for drummers.

Or GMs in tabletop role playing games.

Or prostitutes.

You need prostututes? More than one seems excessive.

I assume that's a hard thing to find for bands? Wouldn't they need to know your music/songs?

Compared to other instruments, a drum kit is expensive, takes up a lot of space, and makes a shit ton of noise. These factors add up to a significant barrier-to-entry to your typical teenage wannabe rock star, who, unless they have unusually supportive parents, will probably just end up getting a guitar (or, these days, downloading a cracked copy of Ableton Live or whatever) instead. This means that drummers are always in short supply.

If you do manage to find one, though, probably 95% of bands would sound "good enough" with pretty much any drummer who could keep time and understood the conventions of their chosen genre.

I mean, if you're writing modern technical metal where the drums are an integral part of the riffs, or prog-rock with lots of tempo changes and odd time signatures, then yeah, a drummer is going to have to actually spend some time learning your songs. But if you're writing those kinds of songs, you probably already have a drummer.

The target audience for an "Uber for drummers" would be young garage bands or middle aged weekend warriors. Think two guitar players (one of whom thinks he can sing) and a bass player (who's either the girlfriend of one of the guitar players or another guitar player whom they talked into playing bass.) They play blues, or classic rock covers, or whatever variety of alternative rock was current when they were in high school. They want to get together an jam on a Saturday afternoon, or they know a guy who can get them a Tuesday night gig down at the Slo-Pitch Tavern, but both of the drummers they know are busy with, you know, real bands.

Guys like that don't need a good drummer, they just need someone who can whack the snare on the 2 and 4 and throw in a fill every eight bars -- which is just the kind of amateur drummer who might be too intimidated to commit to auditioning for a "real" band, but would have nothing to lose and much to gain from a couple hours of casually rocking out with some random amateurs.

Yup. Setup and tear down takes longer too (so practicing at the drummer's place makes more sense). Drummers do the largest share of the work for the least share of respect.

Nah, if they knew anything about music they wouldn't be drummers. They just need to know whether to play too fast or too slow.

(where's my rimshot when I need it?)

Q: How do you get a guitar player to stop playing?
A: Put sheet music in front of him.

Q: How do you get a bass player off your porch?
A: Pay for the pizza.

Q: How many lead singers does it take to change a lightbulb?
A: One. He holds the bulb and the world revolves around him.

A snare drum and a cymbal fell out of a tree.
Ba-dump CHING!
