Explosions In The Sky typify instrumental post rock. Their compositions, that often stretch to ten minutes in length, comprise of intricate, technically sound musicianship characterised by a duelling guitar sound that is both brilliantly epic, wonderfully subdued, melodic, raucous, and at times breathtaking. A skilful avoidance of self indulgence, and just the right amount of commercialism has resulted in a prolonged career, helped in no small part by a relentless commitment to the gruelling schedules of life on the road. Tonight’s show is the second UK date as part of a 5 month world tour – the Texans barely pausing for breath following a similar jaunt in the second half of 2007. An enthusiasm of this nature is essential for a band given the unenviable task of headlining the soul-less cavern that is Bristol’s Anson Rooms. You can’t help but feel that any band playing here are up against it from the start. Ultimately, tonight, Explosions can’t quite overcome the handicaps they are faced with, which is a real shame. But it would be wrong to attribute an underwhelming performance entirely on the substandard venue. Some blame lies with the band themselves.

Interaction is one of the main problems this evening. There are no vantage points in The Anson Rooms meaning that even a clear view of the band proves problematic. This is coupled with a bizarrely quiet stage sound and consequently two of the most essential elements of live performance are largely diminished . The band's lack of audience interaction is normally something to admire – it highlights the absence of bravado, promoting a simplicity that allows the music to do all the talking. But here it seemingly increases the division between band and crowd. It's frustrating, and the frustration is merely compounded by an audience who remain hushed throughout. Instead of creating a poignant atmosphere, the place just feels a bit awkward.

It is testament to the quality of the band's output though that there are still some moments to savour, despite such testing circumstances. Memorial arrives three songs into the eight song set, providing glimpses of what Explosions are capable of. It crackles and twinkles and leads you on a merry dance before unleashing itself with a carefree abandon. Such ferocity still thrills even without the benefits of unfamiliarity.

There were no similar heights reached during the remainder of the performance, only fleeting moments, but given the right surroundings Explosions can be a great live act. Here's hoping they avoid the Anson Rooms the next time they visit these shores.
