Ok so tomorrow night we are doing a little show at a theater in town. During practice we were playing the song Cocaine. The guitarist all did like a improv solo. At the end they told me they wanted me to solo tomorrow night and just improv it. Problem is I don't really know how to exactly solo. I normally just lay down a good groove and play some fills over it. Any tips? It shouldn't be to hard to come up with a solo for this song.
