Splice, a music collaboration service that has yet to fully launch, has raised $2.75 million in angel and venture financing in a seed round led by Union Square Ventures, which has also invested in Turntable.fm. 

Other investors in Splice include True Ventures, Lerer Ventures, SV Angel, First Round Capital, Code Advisors, David Tisch, Rob Wiesenthal and Seth Goldstein. Tisch is founder of BoxGroup, a boutique investment firm based in New York that's also invested in Fab, Boxee and Vine. Wiesenthal is Chief Operating Officer of Warner Music Group and, before that, was Chief Financial Officer of Sony Corp. of America. Goldstein is Chief Executive of DJZ and chairman of Turntable.fm. Andy Weissman, a partner at Union Square Ventures, will join Splice's board.

The service lets artists collaborate in the cloud to create music using digital tools such as Ableton Live, then share their works with fans to solicit feedback, much in the same way SoundCloud is currently used as a sounding board. A partial screenshot of how the service looks is below.

Because Splice's service is just launching in a closed beta on Wednesday and does not yet have paying customers, its investors are likely to be betting as much on the founders as on the business model. Based in New York, Splice was founded by Steve Martocci and Matt Aimonetti. Martocci had co-founded GroupMe, a messaging service that was purchased by Skype in 2011. Tisch was an investor in GroupMe. Aimonetti was a senior engineer at LivingSocial and, before that, a senior staff engineer at Sony Computer Entertainment America.

The company has not disclosed how it plans to generate revenue, although similar services such as Gobbler offer a free, basic tier alongside paid options that have more features.

Artists who want to try out the service must request an invitation at the company's website. Splice plans to solicit feedback from its beta users over the next several weeks before launching to the general public.
