Suggest one obsure album we all should hear

Dust - Hard Attack
Aorta - Aorta
Don Harris - Elevations
Rolling Stones - Liver than You'll Ever Be (bootleg circa 1969 San Fran)
Shadowfax - The Dreams of Children 

CAN - Tago Mago. Not obscure to Krautrock aficionados, but I had no idea they existed until 6 months ago. Truly amazing

Fat Mattress

Thank you. I just listened to some NRBQ & Notorious Cherry Bombs on YouTube. What a hoot & good playing. I really enjoyed the NCB's song "Its Hard To Kiss The Lips (at Night That Chew Your Ass Out All Day Long)" I absolutely Love bands that don't take themselves overly serious. This is a characteristic I believe I see in both bands. And its generally good musicians  who have that quality. After playing in local bands for a long portion of my life, I know its very hard for most local musicians to entertain a crowd

Im sure a genre not yet represented in the myriad of posts, but one that has definitely impacted my 35 year “closed for new material” playlist. 
Genre - Symphonic Metal
Band - Nightwish (lead by the incredible lead singer Floor Jansen)
Album - Storytime (live at Waccen music festival 2013)
