A number of independent bands and artists will perform in the giant soundproof LED glass cube in a series of gigs from 28-31 August at Westfield Stratford City and 6-8 November at Westfield London.
Guests will be able to listen to the music via wireless Sennheiser headphones and experience the bass through the air-blast vibrating floor system. From 20 July, 100 free tickets will be available for each performance.
Auto brand Infinti and KISS FM are also on board as partners.
The Music Cube concept was first launched in September 2014 and performers included Professor Green, MNEK, Jess Glynne and Neon Jungle.
Fiona Kyle, general manager events and entertainment for Westfield UK and US, said: "We are delighted to be bringing Music Cube back to fans for a second year. Last year Music Cube tickets were snapped up within hours, giving lucky fans a chance to connect with artists, sound and bass like never before.
"With major headliners such as Jess Glynne, we expect a similar rush when tickets are released in July. For those who can’t make it down to Westfield, look out for performances being streamed free online."
Gemma Robinson, strategic collaborations manager EMEA at Sennheiser, added: "We are very excited to be part of the Music Cube for the second year running. With music being an integral part of this innovative event, we want to give consumers the best sound experience possible."
