The Hottest 100 Music Festival paints the weekend in shades of competitive euphony as up to 200 bands, artists, and DJs strive for their place in the top 100. For two days, the scenic grounds of Irvine Lake are saturated in 12 unrelenting hours of melody, as bands representing every genre and necktie technique trade barbed jabs and retorting riffs across eight stages. Headlining Saturday's stable of hungry rock hippos, electro hip-hop trio Hyper Crush exercises irrepressible crunkitude, and the mirror-mesmerizing posse of It Boys! taunts audiences by eating multiple servings of songs without gaining weight. Sunday's supernova includes the hardcore crew of Stick to Your Guns, the brawny pop-punk of A Static Lullaby, and a special set from noted headbangers Bleeding Through, whose thrash metal solicits whiplash and spare change to launder a load of black T-shirts.
