Elba, with Gabriel Mintz and The Quit. The Crocodile. 2200 Second Ave., 441-7416. 8 p.m. $8. High-volume indie-rock quintet Elba has seen plenty of shifts since beginning as a trio in 2005, but its guitar-driven melodies accented with bass crescendos, cymbal crashes, and understated vocals have only grown. And though five-track Diplodocus was recorded near the end of 2009, more roster shakeups delayed the release–and any shows since then–until tonight.Coming back after taking a year off means Elba is starting from scratch in many respects. But they’re already in the process of recording their new record, and the outfit has big plans–including translating its notably high-volume and high-energy performances onto wax. They may not have seen commercial success, but if nothing else, their years of playing small venues for small crowds have created a good sense of humor, evidenced by their propensity to discuss 1995 Ben Stiller flick Heavy Weights and British anarcho-rock band Chumbawumba.Follow Reverb on Facebook.
