help me find a band (classic rock-ish)
 

I'm looking for bands from the kind of pre-classic rock era (as in late 50's to mid-late 60's) of bands that have long kind of bluesy keyboarding, a hint of guitars, and almost no vocals. so the whole song is just melodic keyboarding with some drums and rhythm guitar.

cant go wrong with the shadows

the shadows seem kind of jazzy.
