When audience attention is one of the rarest commodities, artists have to be careful about what they release and when. Your double album might be impressive in theory, but you’re not going to find too many people telling you how much they liked track 22 after they clicked your Soundcloud link. You’ll be lucky if they like what they hear enough to make it to track three. Guitar-and-drums duo Yellabird has tackled this concern with a novel approach. Instead of releasing their newest EP Debts all at once, they are making the release of each track an independent event. This method serves bite-size portions to an audience who, in turn, are regularly reminded about the band and their new material. And the material speaks for itself, earning every bit of your attention. Today, the band posted “Dead Hand Blues,” which follows the EP’s first track, “Tired Eyes.” Yellabird will be in NYC and Boston over the next few months.
