Rescheduled by one day and a matter of yards (in case you saw it advertised in last month’s SOURCE and got confused), Brighton’s Diagonal now bring their heady prog immersion to the Albert, in the company of kosmische droners Eat Lights, Become Lights and the retinal pleasures of the Innerstrings Psychedelic Lightshow. Diagonal’s mix of heavy riffing and Hammer House Of Horror organ comes at you via hard rock connoisseurs Rise Above Records, a heavy stamp of quality. (SH)
