HowTo

git clone https://github.com/hzeller/rpi-rgb-led-matrix.git
cd rpi-rgb-led-matrix/utils && make led-image-viewer
cd .. && git clone https://github.com/maxfer1221/python-rgb-matrix
cd python-rgb-matrix && pip3 install -r requirements.txt

I've included an init.sh script which sets up environment variabels and executes the python script to display the album covers. To use it, simply change the {keys} inside init.sh. Alternatively, export KEY_NAME=KEY_VAL each key inside of init.sh and sudo -E python3 ./test.py. Other LED matrix parameters can be changed from within the python script.

Optional:

Create a systemd (or equivalent) service that executes the script on startup/some event.

ex:

[Unit]
Description=Script service to run on wifi connection
Wants=network-online.target
After=network-online.target

[Service]
Type=simple
User=pi
WorkingDirectory=/home/pi
ExecStart=/home/pi/.onWiFi.sh

[Install]
WantedBy=multi-user.target

.onWiFi.sh:

#!/bin/bash
cd /path/to/init.sh
sudo sh init.sh

Then enable the service:

sudo systemctl enable myservice.service
# or: sudo systemctl start myservice.service

Old method

Add the lines inside .bashrc into your ~/.bashrc to automatically start the led display on startup.
