Clubhouse app: what is it and how do you get an invite to the audio app Elon Musk uses?

The exclusive invitation-only social networking app is a hybrid of conference calls, talkback radio and Houseparty

Part talkback radio, part conference call, part Houseparty, Clubhouse is a social networking app based on audio-chat. Users can listen in to conversations, interviews and discussions between interesting people on various topics - it is just like tuning in to a podcast but live and with an added layer of exclusivity.
