Name a great older (before 1990?) musical group you recommend. Thanks.

@TheSirfurryanimalWales Focus: I used to work out the guitar lines from Jan Akkerman - loved playing Hocus Pocus on my guitar, but our singer wasn't ever going to attempt that yodel. I still play Le Clochard as a classical guitar piece now and then when I pick up my nylon string.

@Abstraction Thjiss van Leer still tours playing Focus tunes with a group he dares to call Focus.
And keeps coming up with new Albums.Occasionally there is a good track.
My parents hated Hamburger Concert......no idea why!
And we had a cool music teacher who used to play us Focus tunes😀
