Musicians perform because they have to. It's in the blood and in their soul. It would have to be because no sane human would put themselves through the nightly grind, the travel, the uncertainty and the poverty if they could live doing anything else. But just because it's part of your DNA doesn't mean you shouldn't get paid for your performances. In the "olden" days, musicians counted on their fans to drop money in a tip jar or into an open guitar case on a Subway platform. In 2015, however, very few people carry cash and that percentage drops when you count just the crowd at a club. You could hire someone to stand by the stage and swipe credit cards or you can get ShowSlinger. This mobile app allows fans to tip you with PayPal or ApplePay. Want to give back? Fans can also use the app to request a song in return for their tip. But that's not all! ShowSlinger is also a crowdfunding app. Need a new amp or travel expenses? Create a campaign and watch the dollars roll in. (Okay, it's not quite that easy but it's doable). And when fans follow you on ShowSlinger you can send them text messages, even custom messaging based on location so you can zero in on your target audience. And soon, you'll be able to use ShowSlinger to book gigs right through the app. My son used to be in charge of the bookings for his band and I know he was always stuck in a game of telephone tag right up to the last minute. If ShowSlinger can stop that madness, it truly is a magical tool for musicians. Note: ShowSlinger does take a percentage of any funds you receive through the app and it sounds like there might be some other fees so be sure to read the fine print - which is actually quite humorous - before signing up.
