Installation instructions: gist.github.com/HarryUPf/de42a8d9e2a65e9d7ab5e303b776af6d
Realtime PI: unofficialpi.org/Distros/RealtimePi

Follow those steps to step 7.
Then, continue with these
wget -c https://warmplace.ru/soft/sunvox/sunvox-2.0e.zip
unzip -p sunvox-2.0e.zip sunvox/sunvox/linux_arm_armhf_raspberry_pi/sunvox_lofi [greater than] /home/pi/bin/sunvox_lofi
chmod +x /home/pi/bin/sunvox_lofi /home/pi/bin/sunvox.sh

Now, install glibc 2.29:
cd ~/
sudo apt-get install gawk bison
wget -4c ftp.gnu.org/gnu/glibc/glibc-2.29.tar.gz
tar -zxvf glibc-2.29.tar.gz
mkdir glibc229
cd glibc229
../glibc-2.29/configure --prefix=/opt/glibc
make
make install
export LD_LIBRARY_PATH=/opt/glibc/lib

now, continue with step 8 of the instructions.
In the end, edit sunbox.sh and add export LD_LIBRARY_PATH=/opt/glibc/lib in the third line.

You can now launch Sunvox manually or reboot your PI.

Some bands / artists I've been following for a long time are (among others) Massive Attack, Pink Floyd, Pet Shop Boys, Archive, A-Ha, Yes, Porcupine Tree, John Mellencamp, Jean-Michel Jarre, Metallica, Peter Gabriel and Perturbator. So my music will kind of sound like those (without ever reaching the greatness of those artists, of course). :-)
