RecordTurk.com has compiled a wonderful collection of album art from Turkey's golden era of garage rock and psychedlia (sometime also called Anadolu Rock... an excellent primer can be found here). For the uninitiated, the last few years have seen a flurry of re-issue activity of releases from artists such as Edip Akbayram, Erkin Koray, and 3 Hur-el as well as many comps (Hava Narghile,Turkish Delights, etc.). Unless you have a stoner uncle from Istanbul, much of this music has been extremely hard to come by until the somewhat recent string of re-issues and now on RecordTurk you can browse through all the accompanying album art of the era.
For good measure, here's a mp3 from Edip Akbayram's eponymous 1974 album: Degmen benim gamli yash gonlume (7MB).
Youtube also has a few interesting treats, albeit most of them from the late 70s: there's quite a few videos out there by Boris Manco including the following cheesey video. And when looking for videos for Edip I found a clip with music by Seha Okuş. It appears to be the final few depressing minutes of a 1972 movie called Dönüş.
