Valentina Lisitsa is absolutely amazing. She's got a ton of material on Youtube.
I wasn't trying to say the DT doesn't have any solos. They've got a whole lot of them. It's just that they're not nearly as bombastic as many bands, and they don't take you out of the song as much. The solo I've got in mind is from Amon Amarth's Twilight of the Thunder God. Big, dramatic song. Then you get towards the end, and it's just the rhythm guitar and...something... on top of it. It's a pretty awesome solo, but when it hits, it stops being about the song and it's just about awesome technique. It's not bad, and it works for some bands. But could you imagine Martin or Niklas standing at the front of the stage, arrogantly making awesomeface while they lay an awesome solo down? Most of solos are more modest, or somehow support the song. They're not pure wankery like some bands.
