Singing with backing tracks

Todays's rehearsal was the first time we properly sung through the score using the official backing accompainment we have purchased. This very useful as so far w have just used the Original Cast Recording with the cast singing as well so we hadn't really had a strong feel for timing for vocals or how it actually sounds, minus someone else singing. I can confidently say that everything we sung (up to the end of act 1) went brilliantly and surprising really well. Everyone seemed to know timings, tunes and harmonies perfectly and it honestly sounded great. There were some bits inpaticular that I found challenging in terms of timing and tuning but I eventually was able to correct myself.
A target for myself would just be to make sure that i know all my parts inside out and really revise over any harmonies and timing issues i may be having, in order to get it perfect. I think singing with backing tracks rather than a live band is going to be a bonus, as it allows us to practise and rehearse with the accompainment we are sure to have on the night. It also saves time issues and any worries that may be come about if we were to have a live band - for example, speed changes etc.
