Hallel and Al Hanisim, which I had to learn. Most of Hallel I already knew as the tuneful parts are publicly recited. I just needed to learn a basic nusach for the brachot and chatimot, which was readily available from a number of audio sites online. Al Hanisim I was on my own. Last evening I went through the dry run for the first time. Not elegant, but not tircha d'tzibburah either.
For a congregation that either prides itself or deludes itself into thinking it has a monopoly on serious Jewish talent in our community, the evidence is that AKSE has not done an Ace job in expanding the proficiency that its members bring to the sanctuary. There are a handful of Bar Mitzvah boys who perform capably, though in a limited way, recycling what they learned for their bar mitzvah when convenient, though for all practical purposes never learning a new Haftarah or Torah portion. When the hazzan goes on vacation, he has to hire a Torah reader, one from the Conservative shul, setting aside all his semi-public contempt for inferior conservatives, whose alumni like myself allow AKSE to function from one week to the next. And the unwillingness of the women to advance their skill beyond a Junior Congregation level and the complicity of the Rabbi with this classifies as an institutional shonda from my perspective.
So while those who come early enough to hear what occurs prior to Torah reading will not exactly experience an audio treat, they will have a relatively rare opportunity to listen to an effort to advance skill, one performance that did not derive from the Davening Recycling Center.
