According to my family, "weird and obscure" describes a lot of what I listen to, but I think they're overstating the case. For example, I don't think Afro Celt Sound System or Art of Noise are all that obscure or all that weird. Curve is certainly a bit more obscure, but not really that weird. Same with Sounds from the Ground.
