"I record mostly on a grand--I recorded our first two singles, 'How to Save a Life' and 'Over My Head,' on a Yamaha C7. But we're always challenging ourselves to make it sound a little more approachable. Actually on this third record we're starting to demo a lot of stuff out, and we haven't used the grand yet. We're trying to get away from it, to get a little less of the sweeping, epic sound."

Vanessa Carlton is confirmed to use the Yamaha C7 piano, as listed on the official Yamaha Artists page dedicated to her.

According to YamahaSynth, Stan Lewis uses a Yamaha C7, as well as other Yamaha instruments like the Montage 7 and 8, CP 76, CS Reface, CP Reface, and b2 Upright Piano, as detailed by author Cassie Dennis.

In a YouTube video by Paul Eastham, he showcases the Yamaha C7 Grand Piano while performing "Nearer My God to Thee." The video highlights the piano's use alongside a Strymon Big Sky pedal on the "Cloud" setting.

From an interview with Boom Gaspar and Josh Evans on Keyboard Mag. "For the recording of Lightning Bolt, the rig was completely different, says Evans, and was based on the needs of longtime Pearl Jam producer Brendan O’Brien. 'In the studio, we used a Yamaha C7 grand piano, Hammond B-3 with a Leslie 122, a Korg Triton, and lots of the new digital Mellotron M4000D,' continues Evans. 'Brendan tracks the synths through guitar pedals and analog filters — too many to keep track of here!'"

The C7 at Sweetwater Studios was used for “As Long As I’ve Got Music”, as stated by audio engineer Shawn Dealey in this May 24, 2024 Sweetwater interview.

“For the acoustic piano, on our Yamaha C7, we paired a single Neumann U 67 with the Warm Audio WA-2MPX tube preamp and the Chandler Limited RS660 for tube compression.”
