Avid music fans are always looking for ways to connect with their favorite artist. Some follow a band from city to city during concert tours; others obsess over every record, bootleg recording, Facebook post and Instagram photo they can find of a musician’s performance.

Now a growing number of fans are discovering and collecting “rhythm-on-canvas” art, where drummers from some big-name bands — like Guns N’ Roses and the Red Hot Chili Peppers — use LED technology to transfer their unique style and rhythm of drumming onto a canvas. SceneFour, a Los Angeles design and branding firm, started making them in 2011. They’re part of a growing movement to use technology to turn nonvisual media into visual art.

The art provides a “musical fingerprint” that is as unique as an artist’s autograph.

“Each artist has their own persona, their own way of moving, their own physical stature and their own energy, so all these come into play,” said Cindy Blackman Santana , a jazz artist who was also a touring drummer for Lenny Kravitz and Santana, and one of the drummers captured by SceneFour.
