My name is Evan Jaslow and I'm the former Prog Guru of OnlineDrummer. Nowadays I have my own website where I sell my drum transcriptions. Naturally, I specialize in progressive rock, with my most notable product being a full transcription of Dream Theater's Images and Words. As a whole my selection isn't huge, but what I do have is top-quality as I spend a lot of time (possibly too much) proofreading and re-uploading new versions. There's a selection of free material for download as well, and I do take requests for a fee.
Thanks for reading!
