🎼 Matt Mangels 🎹

This is my homepage. There are many like it but this one is mine.

Welcome to the personal website of Sean Matthew “Mangels” Hall. I’m primarily a musician (keyboards and vocals) but I also tinker with software now and then.

New Music!

Thanks to everyone who came to my show presented by Sunset Music & Arts! I should have some footage from that show on here soon. In the meantime, here's a new song I wrote and recorded:
Incel by Starlight (That’s How I Named This Song) (MP3 download)

Music

All My Exes Live in Texas (Sanger D. Shafer/Lyndia J. Shafer) — Live at Hotel Utah, June 23, 2014
Lonely (original song) — Live at Hotel Utah, May 8, 2017

Elegy For Armando — Improvisation from February 2021 in honor of Armando “Chick” Corea.
Solo piano cover of XTC's “Chalkhills & Children” — Approved by Andy Partridge himself! He has since deleted his Twitter account and thus I can't link to the tweet where he said this, so you'll have to take my word for it!
“Fantastic work man ! that is marvellous, don't know how you do it, my piano playing is Neanderthal up to that. Beautiful, well done.”
The Come Up — I came up with the melody and chord progression to this beat that was produced by local rapper JC (c. 2010)

Software

Countdown — Based on the UK game show of the same name (no copyright infringment intended!)
CA Counties — How many of California's 58 counties can you name? Play this game to find out!
SF Daily Weather Records — The record High/Low temperatures and precipitation for San Francisco on today's date. Formerly a bot that posted to Mastodon.
Temperatures Around the Bay — A map of live temperatures from more than a dozen different weather stations in the greater San Francisco Bay Area. UPDATE June 2025: the API from the NWS I was using is not currently functional, possibly due to DOGE-related fuckery.
WordHole — Guess the 5 letter word
afd_to_json — A Python script that takes an Area Forecast Discussion (AFD) from the National Weather Service and turns it into JSON. Currently only works with Forecasts from the MTR office (San Francisco/Monterey Bay Area).

Miscellaneous Content

Why Won't Google Mark Atherton Station as Closed? — The curious case of why a train station that closed 4+ years ago is still listed as an open, active station on Google Maps.
Name Drops in Elton John's lyrics — Elton's lyricist Bernie Taupin loves to name-drop; this is a partial list of all the names mentioned in Elton's work.
