Glitterer is a band from Washington, D.C. Initially, and for some time, it was a solo project: a man and his laptop, with occasional in-studio and onstage assistance from other human beings. Four records, including two full-length albums on Anti-, were released in that one-guy period. But now Glitterer is a band: four charter members writing and recording songs and performing them at shows together, driving around the country, getting on each other’s nerves. Road cases piled in the van. Soundcheck at 5 p.m. Merch in the back. A band. You’re familiar with bands? Glitterer is one of those. They play loud melodic post-hardcore rock music that can sometimes seem simple but is always subtly weird and complex. Their new 12-song LP, Rationale, will be out on Anti- on Feb. 23, 2024.
