I've been trawling through the archives but can't find this strip - would you guys be able to help?

I'm looking for a strip where Teodor (I think) is listening to a psychedelic / prog rock album and loving it. Until Lyle(?) tells him to check some other albums by the same band, which leads to the realization that the band is actually crap.

Anyone know what date this was published?
Or post any vague memories of the name of the band / other clues that might help me find it!

Thanks a lot in advance
G
