Ok I consider myself a reasonable bass player, can play by ear, learn songs almost instantly, tell when changes are to occur when playing things I don't know etc.
Now I'd consider myself a groove bass player, I can fancy things up or add highly melodic bits but I mainly groove and flow around.
So I just got listening to Mastodon again and started playing to a few songs, especially colony of birchmen.
Now I can play all of it flat out pretty perfect, although it's not fast but just at the end, just before the big bridge heavy ending thing (no idea what else to call it

) the bass player does an incredibly fast line, now I've fiddled with it, I know the notes but not for the life of me can my fingers on my fretting and fingering hands get that speed.
Most people say I'm fast at throwing pentatonic esque etc gear into bass lines without loosing any feel or groove but god damn this guys little tiny speed fills (doesn't seem an often occurrence) are a killer for me.
Maybe I should join a speed metal band and sweat balls all night hoping to keep up

.
If anyone has some knowledge of the song and have tried etc how do you go. I'm sure most can shred a bass quicker than I can change channels.
