Nick Rossi heard an uncredited rhythm guitar on Dizzy Gillespie's 1946 Musicraft recording of Emanon. Source separation pulls it out of the band: seven transfers, every guitar stem ranked and playable.

<p>Nick Rossi heard an uncredited rhythm guitar on Dizzy Gillespie's 1946 Musicraft recording of Emanon, a session with no guitarist listed in the standard discographies. Source separation pulls it out of the band: seven transfers, two separation passes, every guitar stem ranked and playable, with a mixer to solo the part or rebalance the mix.</p><p><a href="https://charlesperforms.com/blog/emanon/">Read the full post</a></p> https://charlesperforms.com/blog/clyde-hart/ 2026-07-21T12:00:00-07:00 2026-07-24T12:00:00-07:00

The pianist on bebop's founding record dates, and almost nobody says his name. The stem mixer in the post lets you solo Hart's piano across 121 sides from 32 sessions, 1936 to 1945.

<p>Every history of bebop has the same cast on the piano bench, but put on the records where the music actually arrives and the pianist is usually Clyde Hart. A profile of the swing-to-bop transition's purest case, with a stem mixer that lets you solo Hart's piano across 121 sides from 32 sessions, from Billie Holiday in 1936 to "Groovin' High" in 1945.</p><p><a href="https://charlesperforms.com/blog/clyde-hart/">Read and listen</a></p> https://charlesperforms.com/blog/welcome/ 2026-07-20T12:00:00-07:00 2026-07-24T12:00:00-07:00

Why I'm starting a blog: jazz piano teaching and practice, early jazz transcription projects, lesser-known pianists, and the software behind them.

<p>For fifteen-odd years, most of my writing has lived in setlists, lead sheets, and the occasional liner note. This page is for the rest of it: ideas from the teaching studio and the practice room, early jazz transcription projects like the King Oliver 1923 critical edition, lesser-known pianists, and the software behind them.</p><p><a href="https://charlesperforms.com/blog/welcome/">Read the full post</a></p>
