Ok so with the drums, how many mics is he planning on using? I think internal is out of the question here.
Some to look at would be the Focusrite Scarlett series and the M-Audio Fastrack series. Can't really go wrong with either of these though I found the Scarlett to be more transparent. Whichever one has enough inputs to do the job would be the one to get. If he can spend more then maybe look at MOTU or RME interfaces. Generally recording drums is a fairly expensive process.
