Hotspur returns for another energetic headlining gig at the venerated hometown 9:30 Club. The band’s brand of Coldplay-eseque pop-rock is so catchy, the melodies and hooks so ingratiating, the vocals of Joe Mach and the synths of Dave Trichter so pristinely clear and crisp, you can't help but be a little suspicious. How do we know this band's five members aren't lobbyists or researchers seeing if they can game the pop system? Well, if this is a game, the band wins. Friday, Sept. 3. Four other bands open. Doors at 8:30 p.m. Nightclub 9:30, 815 V St. NW. Tickets are $15. Call 202-265-0930 or visit 930.com.
