East-West by the Butterfield Blues Band
and other long mostly instrumental rock. Pink Floyd Animals is great! I also like Ravi Shankar, Canned Heat Refried Boogie, America by The Nice, The Gumbo Variations by Frank Zappa, Sweet Child by The Pentangle, any Lorenna McKennitt, CSN&Y Four Way Street album.
And lots more. I'm sure I'm dating myself, this is all pretty ancient rock π
