When announcing Mezzanine's 21st anniversary, Massive Attack founding member Robert Del Naja billed these shows as '…our own personalised nostalgia nightmare head trip'. The group's third album almost tore them apart, and the resulting document reflects not only this internal fracture but also the torrid world outside, as we collectively plunged into the media-obsessed and hyperconnected society of today. Reflecting this 'nightmare head trip', the group enlisted renowned documentarian Adam Curtis (HyperNormalisation to provide visuals. Within minutes of the show opening, it became clear that Curtis is an integral part of these shows, as archive footage flickered on screen and big picture statements such as 'ONCE UPON A TIME DATA WOULD SET US FREE' are emblazoned onscreen in large white font.

The band eschew the normal anniversary album playthrough and instead perform Mezzanine out of order, with surprisingly faithful covers of songs sampled on the original album (The Velvet Underground's 'I Found a Reason', The Cure's '10:15 on a Saturday Night' and Ultravox's 'Rockwrok' all make appearances). However, it is when they plunge into album tracks such as 'Risingson', 'Black Milk' and a huge 'Ineartia Creeps' that the show comes alight.

Special guests Horace Andy and Elizabeth Fraser add a lot to the show, the former coolly anchoring the ebb and flow of album opener Angel and the latter's ethereal vocals bringing some light to the unrelenting darkness of the night. The album's centre point, 'Teardrop' sounds even more heart-wrenching live, underpinned by a subtle light design which allow Fraser's voice to conjure its own imagery.

The show was a unique way for the group to celebrate an album that does not sound its age. At times the evening erred too close to a live Adam Curtis film, and it is clear that the crowd is itching for some non-Mezzanine hits. Yet as a way for a band to celebrate its legacy whilst avoiding the clichés of a heritage act, it is a success.
