There’s something inherently alluring about The Tontons. Maybe it’s the vocals of frontwoman Asli Omar, sometimes teeth-hurting dulcet coos, other times lower-register crushed velvet moans, murmurs and humming intones. Or perhaps the Houston band’s music is responsible; difficult to really pin down but in essence, indie rock coated in light garage, Southern blues, psychedelia and pop flavors. Either way, Tontons are definitely a band to keep an eye on. Also performing: Sonic Graffiti, Caleb Hayers Band.
