Mellow man Mac DeMarco continues to crank out new music and beast all over the festival circuit. The man might give the impression that he’s floating carelessly through life, but he’s got a work ethic. DeMarco is a week and a half away from releasing his new album Here Comes The Cowboy, and he’s now doing the promo-circuit thing. Last night, he was the musical guest on Jimmy Fallon’s Tonight Show, where he had the confidence to broadcast goofy charm all over the room and look like he just rolled out of bed.

On the show, DeMarco sang “All Of Our Yesterdays,” the song that he says was his attempt to write an Oasis song. You’re not going to believe this, but it doesn’t sound anything like an Oasis song. DeMarco played all the instruments on the recorded version. But at the Tonight Show, DeMarco didn’t play any instruments — at least until the end of the song, when he finally strapped on a guitar and busted out a discordantly bluesy solo. It’s weird watching DeMarco sing without a guitar; his current move is to do a sort of butt-dip dance while singing. Watch it below.

In other DeMarco news, DeMarco, in his new Billboard profile, has some helpful advice for other independent artists:

Put this in the interview: Do not sign a 360 deal. I don’t care how much money they’re offering you, don’t [take it]. It’s an awful, awful idea. It’s a long time, a really long time. And they own your image. They take money from your merch on tour — nobody should touch that. I didn’t know that some bands don’t own their merch, which to me is like — straight up, you’re being robbed. You can make money selling merch at shows, so it’s good if you own it. Thumbs up, bonus for you. Do not give anybody that merch money, or your show money. They’re not on the stage, and they’re probably not even in the city [you’re playing]. Forget about it.

Here Comes The Cowboy is out 5/10 on Mac’s Record Label.
