Query: Cool stuff from an underrated band

One of the best Chicago bands of the early 90s, Lava Sutra never got the breaks or the acclaim they truly deserved. Hard N Heavy, their only album, was recorded slightly after their prime (they had previously released two AMAZING singles on their own Bold Records label), but it's still full of innovative hard rock songs with psychedelic, glam and pop overtones. Several Lava Sutra members are now in the Chamber Strings, whose Gospel Morning CD made a lot of year-end top ten lists for 1999.
